OffsetTime

class OffsetTime : Temporal, TemporalAdjuster, Comparable<OffsetTime!>, Serializable
kotlin.Any
   ↳ java.time.OffsetTime

A time with an offset from UTC/Greenwich in the ISO-8601 calendar system, such as 10:15:30+01:00.

OffsetTime is an immutable date-time object that represents a time, often viewed as hour-minute-second-offset. This class stores all time fields, to a precision of nanoseconds, as well as a zone offset. For example, the value "13:45:30.123456789+02:00" can be stored in an OffsetTime.

Public methods

adjustInto

Added in API level 26
fun adjustInto(temporal: Temporal!): Temporal!

Adjusts the specified temporal object to have the same offset and time as this object.

This returns a temporal object of the same observable type as the input with the offset and time changed to be the same as this.

The adjustment is equivalent to using Temporal#with(TemporalField, long) twice, passing ChronoField#NANO_OF_DAY and ChronoField#OFFSET_SECONDS as the fields.

In most cases, it is clearer to reverse the calling pattern by using Temporal#with(TemporalAdjuster):

// these two lines are equivalent, but the second approach is recommended
    temporal = thisOffsetTime.adjustInto(temporal);
    temporal = temporal.with(thisOffsetTime);
  

This instance is immutable and unaffected by this method call.

Parameters
temporal Temporal!: the target object to be adjusted, not null
Return
Temporal! the adjusted object, not null
Exceptions
java.time.DateTimeException if unable to make the adjustment
java.lang.ArithmeticException if numeric overflow occurs

atDate

Added in API level 26
fun atDate(date: LocalDate!): OffsetDateTime!

Combines this time with a date to create an OffsetDateTime.

This returns an OffsetDateTime formed from this time and the specified date. All possible combinations of date and time are valid.

Parameters
date LocalDate!: the date to combine with, not null
Return
OffsetDateTime! the offset date-time formed from this time and the specified date, not null

compareTo

Added in API level 26
fun compareTo(other: OffsetTime!): Int

Compares this OffsetTime to another time.

The comparison is based first on the UTC equivalent instant, then on the local time. It is "consistent with equals", as defined by Comparable.

For example, the following is the comparator order:

  1. 10:30+01:00
  2. 11:00+01:00
  3. 12:00+02:00
  4. 11:30+01:00
  5. 12:00+01:00
  6. 12:30+01:00
Values #2 and #3 represent the same instant on the time-line. When two values represent the same instant, the local time is compared to distinguish them. This step is needed to make the ordering consistent with equals().

To compare the underlying local time of two TemporalAccessor instances, use ChronoField#NANO_OF_DAY as a comparator.

Parameters
o the object to be compared.
other OffsetTime!: the other time to compare to, not null
Return
Int the comparator value, negative if less, positive if greater
Exceptions
java.lang.NullPointerException if the specified object is null
java.lang.ClassCastException if the specified object's type prevents it from being compared to this object.

equals

Added in API level 26
fun equals(other: Any?): Boolean

Checks if this time is equal to another time.

The comparison is based on the local-time and the offset. To compare for the same instant on the time-line, use isEqual(java.time.OffsetTime).

Only objects of type OffsetTime are compared, other types return false. To compare the underlying local time of two TemporalAccessor instances, use ChronoField#NANO_OF_DAY as a comparator.

Parameters
obj the object to check, null returns false
Return
Boolean true if this is equal to the other time

format

Added in API level 26
fun format(formatter: DateTimeFormatter!): String!

Formats this time using the specified formatter.

This time will be passed to the formatter to produce a string.

Parameters
formatter DateTimeFormatter!: the formatter to use, not null
Return
String! the formatted time string, not null
Exceptions
java.time.DateTimeException if an error occurs during printing

from

Added in API level 26
static fun from(temporal: TemporalAccessor!): OffsetTime!

Obtains an instance of OffsetTime from a temporal object.

This obtains an offset time based on the specified temporal. A TemporalAccessor represents an arbitrary set of date and time information, which this factory converts to an instance of OffsetTime.

The conversion extracts and combines the ZoneOffset and the LocalTime from the temporal object. Implementations are permitted to perform optimizations such as accessing those fields that are equivalent to the relevant objects.

This method matches the signature of the functional interface TemporalQuery allowing it to be used as a query via method reference, OffsetTime::from.

Parameters
temporal TemporalAccessor!: the temporal object to convert, not null
Return
OffsetTime! the offset time, not null
Exceptions
java.time.DateTimeException if unable to convert to an OffsetTime

get

Added in API level 26
fun get(field: TemporalField!): Int

Gets the value of the specified field from this time as an int.

This queries this time for the value of the specified field. The returned value will always be within the valid range of values for the field. If it is not possible to return the value, because the field is not supported or for some other reason, an exception is thrown.

If the field is a ChronoField then the query is implemented here. The supported fields will return valid values based on this time, except NANO_OF_DAY and MICRO_OF_DAY which are too large to fit in an int and throw an UnsupportedTemporalTypeException. All other ChronoField instances will throw an UnsupportedTemporalTypeException.

If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.getFrom(TemporalAccessor) passing this as the argument. Whether the value can be obtained, and what the value represents, is determined by the field.

Parameters
field TemporalField!: the field to get, not null
Return
Int the value for the field
Exceptions
java.time.DateTimeException if a value for the field cannot be obtained or the value is outside the range of valid values for the field
java.time.temporal.UnsupportedTemporalTypeException if the field is not supported or the range of values exceeds an int
java.lang.ArithmeticException if numeric overflow occurs

getHour

Added in API level 26
fun getHour(): Int

Gets the hour-of-day field.

Return
Int the hour-of-day, from 0 to 23

getLong

Added in API level 26
fun getLong(field: TemporalField!): Long

Gets the value of the specified field from this time as a long.

This queries this time for the value of the specified field. If it is not possible to return the value, because the field is not supported or for some other reason, an exception is thrown.

If the field is a ChronoField then the query is implemented here. The supported fields will return valid values based on this time. All other ChronoField instances will throw an UnsupportedTemporalTypeException.

If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.getFrom(TemporalAccessor) passing this as the argument. Whether the value can be obtained, and what the value represents, is determined by the field.

Parameters
field TemporalField!: the field to get, not null
Return
Long the value for the field
Exceptions
java.time.DateTimeException if a value for the field cannot be obtained
java.time.temporal.UnsupportedTemporalTypeException if the field is not supported

isAfter

Added in API level 26
fun isAfter(other: OffsetTime!): Boolean

Checks if the instant of this OffsetTime is after that of the specified time applying both times to a common date.

This method differs from the comparison in compareTo in that it only compares the instant of the time. This is equivalent to converting both times to an instant using the same date and comparing the instants.

Parameters
other OffsetTime!: the other time to compare to, not null
Return
Boolean true if this is after the instant of the specified time

isBefore

Added in API level 26
fun isBefore(other: OffsetTime!): Boolean

Checks if the instant of this OffsetTime is before that of the specified time applying both times to a common date.

This method differs from the comparison in compareTo in that it only compares the instant of the time. This is equivalent to converting both times to an instant using the same date and comparing the instants.

Parameters
other OffsetTime!: the other time to compare to, not null
Return
Boolean true if this is before the instant of the specified time

isEqual

Added in API level 26
fun isEqual(other: OffsetTime!): Boolean

Checks if the instant of this OffsetTime is equal to that of the specified time applying both times to a common date.

This method differs from the comparison in compareTo and equals in that it only compares the instant of the time. This is equivalent to converting both times to an instant using the same date and comparing the instants.

Parameters
other OffsetTime!: the other time to compare to, not null
Return
Boolean true if this is equal to the instant of the specified time

isSupported

Added in API level 26
fun isSupported(field: TemporalField!): Boolean

Checks if the specified field is supported.

This checks if this time can be queried for the specified field. If false, then calling the range, get and with(java.time.temporal.TemporalField,long) methods will throw an exception.

If the field is a ChronoField then the query is implemented here. The supported fields are:

  • NANO_OF_SECOND
  • NANO_OF_DAY
  • MICRO_OF_SECOND
  • MICRO_OF_DAY
  • MILLI_OF_SECOND
  • MILLI_OF_DAY

  • CLOCK_HOUR_OF_AMPM
  • HOUR_OF_DAY
  • CLOCK_HOUR_OF_DAY
  • AMPM_OF_DAY
  • OFFSET_SECONDS
All other ChronoField instances will return false.

If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.isSupportedBy(TemporalAccessor) passing this as the argument. Whether the field is supported is determined by the field.

Parameters
field TemporalField!: the field to check, null returns false
Return
Boolean true if the field is supported on this time, false if not

isSupported

Added in API level 26
fun isSupported(unit: TemporalUnit!): Boolean

Checks if the specified unit is supported.

This checks if the specified unit can be added to, or subtracted from, this offset-time. If false, then calling the plus(long,java.time.temporal.TemporalUnit) and minus methods will throw an exception.

If the unit is a ChronoUnit then the query is implemented here. The supported units are:

  • NANOS
  • MICROS
  • MILLIS
  • SECONDS
  • MINUTES
  • HOURS
  • HALF_DAYS
All other ChronoUnit instances will return false.

If the unit is not a ChronoUnit, then the result of this method is obtained by invoking TemporalUnit.isSupportedBy(Temporal) passing this as the argument. Whether the unit is supported is determined by the unit.

Parameters
unit TemporalUnit!: the unit to check, null returns false
Return
Boolean true if the unit can be added/subtracted, false if not

minus

Added in API level 26
fun minus(amountToSubtract: TemporalAmount!): OffsetTime!

Returns a copy of this time with the specified amount subtracted.

This returns an OffsetTime, based on this one, with the specified amount subtracted. The amount is typically Duration but may be any other type implementing the TemporalAmount interface.

The calculation is delegated to the amount object by calling TemporalAmount#subtractFrom(Temporal). The amount implementation is free to implement the subtraction in any way it wishes, however it typically calls back to minus(long,java.time.temporal.TemporalUnit). Consult the documentation of the amount implementation to determine if it can be successfully subtracted.

This instance is immutable and unaffected by this method call.

Parameters
amount the amount to subtract, not null
amountToSubtract TemporalAmount!: the amount to subtract, not null
Return
OffsetTime! an OffsetTime based on this time with the subtraction made, not null
Exceptions
java.time.DateTimeException if the subtraction cannot be made

minus

Added in API level 26
fun minus(
    amountToSubtract: Long,
    unit: TemporalUnit!
): OffsetTime!

Returns a copy of this time with the specified amount subtracted.

This returns an OffsetTime, based on this one, with the amount in terms of the unit subtracted. If it is not possible to subtract the amount, because the unit is not supported or for some other reason, an exception is thrown.

This method is equivalent to plus(long,java.time.temporal.TemporalUnit) with the amount negated. See that method for a full description of how addition, and thus subtraction, works.

This instance is immutable and unaffected by this method call.

Parameters
amountToSubtract Long: the amount of the unit to subtract from the result, may be negative
unit TemporalUnit!: the unit of the amount to subtract, not null
Return
OffsetTime! an OffsetTime based on this time with the specified amount subtracted, not null

now

Added in API level 26
static fun now(): OffsetTime!

Obtains the current time from the system clock in the default time-zone.

This will query the system clock in the default time-zone to obtain the current time. The offset will be calculated from the time-zone in the clock.

Using this method will prevent the ability to use an alternate clock for testing because the clock is hard-coded.

Return
OffsetTime! the current time using the system clock and default time-zone, not null

now

Added in API level 26
static fun now(zone: ZoneId!): OffsetTime!

Obtains the current time from the system clock in the specified time-zone.

This will query the system clock to obtain the current time. Specifying the time-zone avoids dependence on the default time-zone. The offset will be calculated from the specified time-zone.

Using this method will prevent the ability to use an alternate clock for testing because the clock is hard-coded.

Parameters
zone ZoneId!: the zone ID to use, not null
Return
OffsetTime! the current time using the system clock, not null

now

Added in API level 26
static fun now(clock: Clock!): OffsetTime!

Obtains the current time from the specified clock.

This will query the specified clock to obtain the current time. The offset will be calculated from the time-zone in the clock.

Using this method allows the use of an alternate clock for testing. The alternate clock may be introduced using dependency injection.

Parameters
clock Clock!: the clock to use, not null
Return
OffsetTime! the current time, not null

of

Added in API level 26
static fun of(
    time: LocalTime!,
    offset: ZoneOffset!
): OffsetTime!

Obtains an instance of OffsetTime from a local time and an offset.

Parameters
time LocalTime!: the local time, not null
offset ZoneOffset!: the zone offset, not null
Return
OffsetTime! the offset time, not null

of

static fun of(
    hour: Int,
    minute: Int,
    second: Int,
    nanoOfSecond: Int,
    offset: ZoneOffset!
): OffsetTime!

Obtains an instance of OffsetTime from an hour, minute, second and nanosecond.

This creates an offset time with the four specified fields.

This method exists primarily for writing test cases. Non test-code will typically use other methods to create an offset time. LocalTime has two additional convenience variants of the equivalent factory method taking fewer arguments. They are not provided here to reduce the footprint of the API.

Parameters
hour Int: the hour-of-day to represent, from 0 to 23
minute Int: the minute-of-hour to represent, from 0 to 59
second Int: the second-of-minute to represent, from 0 to 59
nanoOfSecond Int: the nano-of-second to represent, from 0 to 999,999,999
offset ZoneOffset!: the zone offset, not null
Return
OffsetTime! the offset time, not null
Exceptions
java.time.DateTimeException if the value of any field is out of range

ofInstant

Added in API level 26
static fun ofInstant(
    instant: Instant!,
    zone: ZoneId!
): OffsetTime!

Obtains an instance of OffsetTime from an Instant and zone ID.

This creates an offset time with the same instant as that specified. Finding the offset from UTC/Greenwich is simple as there is only one valid offset for each instant.

The date component of the instant is dropped during the conversion. This means that the conversion can never fail due to the instant being out of the valid range of dates.

Parameters
instant Instant!: the instant to create the time from, not null
zone ZoneId!: the time-zone, which may be an offset, not null
Return
OffsetTime! the offset time, not null

parse

Added in API level 26
static fun parse(text: CharSequence!): OffsetTime!

Obtains an instance of OffsetTime from a text string such as 10:15:30+01:00.

The string must represent a valid time and is parsed using java.time.format.DateTimeFormatter#ISO_OFFSET_TIME.

Parameters
text CharSequence!: the text to parse such as "10:15:30+01:00", not null
Return
OffsetTime! the parsed local time, not null
Exceptions
java.time.format.DateTimeParseException if the text cannot be parsed

parse

Added in API level 26
static fun parse(
    text: CharSequence!,
    formatter: DateTimeFormatter!
): OffsetTime!

Obtains an instance of OffsetTime from a text string using a specific formatter.

The text is parsed using the formatter, returning a time.

Parameters

formatter DateTimeFormatter!: the formatter to use, not null
Return
OffsetTime! the parsed offset time, not null
Exceptions
java.time.format.DateTimeParseException if the text cannot be parsed

plus

Added in API level 26
fun plus(amountToAdd: TemporalAmount!): OffsetTime!

Returns a copy of this time with the specified amount added.

This returns an OffsetTime, based on this one, with the specified amount added. The amount is typically Duration but may be any other type implementing the TemporalAmount interface.

The calculation is delegated to the amount object by calling TemporalAmount#addTo(Temporal). The amount implementation is free to implement the addition in any way it wishes, however it typically calls back to plus(long,java.time.temporal.TemporalUnit). Consult the documentation of the amount implementation to determine if it can be successfully added.

This instance is immutable and unaffected by this method call.

Parameters
amount the amount to add, not null
amountToAdd TemporalAmount!: the amount to add, not null
Return
OffsetTime! an OffsetTime based on this time with the addition made, not null
Exceptions
java.time.DateTimeException if the addition cannot be made
java.lang.ArithmeticException if numeric overflow occurs

plus

Added in API level 26
fun plus(
    amountToAdd: Long,
    unit: TemporalUnit!
): OffsetTime!

Returns a copy of this time with the specified amount added.

This returns an OffsetTime, based on this one, with the amount in terms of the unit added. If it is not possible to add the amount, because the unit is not supported or for some other reason, an exception is thrown.

If the field is a ChronoUnit then the addition is implemented by LocalTime#plus(long, TemporalUnit). The offset is not part of the calculation and will be unchanged in the result.

If the field is not a ChronoUnit, then the result of this method is obtained by invoking TemporalUnit.addTo(Temporal, long) passing this as the argument. In this case, the unit determines whether and how to perform the addition.

This instance is immutable and unaffected by this method call.

Parameters
amountToAdd Long: the amount of the unit to add to the result, may be negative
unit TemporalUnit!: the unit of the amount to add, not null
Return
OffsetTime! an OffsetTime based on this time with the specified amount added, not null

The result of this method is obtained by invoking the TemporalQuery#queryFrom(TemporalAccessor) method on the specified query passing this as the argument.

Parameters
<R> the type of the result
query TemporalQuery<R>!: the query to invoke, not null
Return
R the query result, null may be returned (defined by the query)
Exceptions
java.time.DateTimeException if unable to query (defined by the query)
java.lang.ArithmeticException if numeric overflow occurs (defined by the query)

range

Added in API level 26
fun range(field: TemporalField!): ValueRange!

Gets the range of valid values for the specified field.

The range object expresses the minimum and maximum valid values for a field. This time is used to enhance the accuracy of the returned range. If it is not possible to return the range, because the field is not supported or for some other reason, an exception is thrown.

If the field is a ChronoField then the query is implemented here. The supported fields will return appropriate range instances. All other ChronoField instances will throw an UnsupportedTemporalTypeException.

If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.rangeRefinedBy(TemporalAccessor) passing this as the argument. Whether the range can be obtained is determined by the field.

Parameters
field TemporalField!: the field to query the range for, not null
Return
ValueRange! the range of valid values for the field, not null
Exceptions
java.time.DateTimeException if the range for the field cannot be obtained
java.time.temporal.UnsupportedTemporalTypeException if the field is not supported

toEpochSecond

Added in API level 34
fun toEpochSecond(date: LocalDate!): Long

Converts this OffsetTime to the number of seconds since the epoch of 1970-01-01T00:00:00Z.

This combines this offset time with the specified date to calculate the epoch-second value, which is the number of elapsed seconds from 1970-01-01T00:00:00Z. Instants on the time-line after the epoch are positive, earlier are negative.

Parameters
date LocalDate!: the localdate, not null
Return
Long the number of seconds since the epoch of 1970-01-01T00:00:00Z, may be negative

toLocalTime

Added in API level 26
fun toLocalTime(): LocalTime!

Gets the LocalTime part of this date-time.

This returns a LocalTime with the same hour, minute, second and nanosecond as this date-time.

Return
LocalTime! the time part of this date-time, not null

toString

Added in API level 26
fun toString(): String

Outputs this time as a String, such as 10:15:30+01:00.

The output will be one of the following ISO-8601 formats:

  • HH:mmXXXXX
  • HH:mm:ssXXXXX
  • HH:mm:ss.SSSXXXXX
  • HH:mm:ss.SSSSSSXXXXX
  • HH:mm:ss.SSSSSSSSSXXXXX
The format used will be the shortest that outputs the full value of the time where the omitted parts are implied to be zero.
Return
String a string representation of this time, not null

truncatedTo

Added in API level 26
fun truncatedTo(unit: TemporalUnit!): OffsetTime!

Returns a copy of this OffsetTime with the time truncated.

Truncation returns a copy of the original time with fields smaller than the specified unit set to zero. For example, truncating with the minutes unit will set the second-of-minute and nano-of-second field to zero.

The unit must have a duration that divides into the length of a standard day without remainder. This includes all supplied time units on ChronoUnit and DAYS. Other units throw an exception.

The offset does not affect the calculation and will be the same in the result.

This instance is immutable and unaffected by this method call.

Parameters
unit TemporalUnit!: the unit to truncate to, not null
Return
OffsetTime! an OffsetTime based on this time with the time truncated, not null
Exceptions
java.time.DateTimeException if unable to truncate
java.time.temporal.UnsupportedTemporalTypeException if the unit is not supported

until

Added in API level 26
fun until(
    endExclusive: Temporal!,
    unit: TemporalUnit!
): Long

Calculates the amount of time until another time in terms of the specified unit.

This calculates the amount of time between two OffsetTime objects in terms of a single TemporalUnit. The start and end points are this and the specified time. The result will be negative if the end is before the start. For example, the amount in hours between two times can be calculated using startTime.until(endTime, HOURS).

The Temporal passed to this method is converted to a OffsetTime using from(java.time.temporal.TemporalAccessor). If the offset differs between the two times, then the specified end time is normalized to have the same offset as this time.

The calculation returns a whole number, representing the number of complete units between the two times. For example, the amount in hours between 11:30Z and 13:29Z will only be one hour as it is one minute short of two hours.

There are two equivalent ways of using this method. The first is to invoke this method. The second is to use TemporalUnit#between(Temporal, Temporal):

// these two lines are equivalent
    amount = start.until(end, MINUTES);
    amount = MINUTES.between(start, end);
  
The choice should be made based on which makes the code more readable.

The calculation is implemented in this method for ChronoUnit. The units NANOS, MICROS, MILLIS, SECONDS, MINUTES, HOURS and HALF_DAYS are supported. Other ChronoUnit values will throw an exception.

If the unit is not a ChronoUnit, then the result of this method is obtained by invoking TemporalUnit.between(Temporal, Temporal) passing this as the first argument and the converted input temporal as the second argument.

This instance is immutable and unaffected by this method call.

Parameters
endExclusive Temporal!: the end time, exclusive, which is converted to an OffsetTime, not null
unit TemporalUnit!: the unit to measure the amount in, not null
Return
Long the amount of time between this time and the end time
Exceptions
java.time.DateTimeException if the amount cannot be calculated, or the end temporal cannot be converted to an OffsetTime
java.time.temporal.UnsupportedTemporalTypeException if the unit is not supported
java.lang.ArithmeticException if numeric overflow occurs

with

Added in API level 26
fun with(adjuster: TemporalAdjuster!): OffsetTime!

Returns an adjusted copy of this time.

This returns an OffsetTime, based on this one, with the time adjusted. The adjustment takes place using the specified adjuster strategy object. Read the documentation of the adjuster to understand what adjustment will be made.

A simple adjuster might simply set the one of the fields, such as the hour field. A more complex adjuster might set the time to the last hour of the day.

The classes LocalTime and ZoneOffset implement TemporalAdjuster, thus this method can be used to change the time or offset:

result = offsetTime.with(time);
   result = offsetTime.with(offset);
  

The result of this method is obtained by invoking the TemporalAdjuster#adjustInto(Temporal) method on the specified adjuster passing this as the argument.

This instance is immutable and unaffected by this method call.

Parameters
adjuster TemporalAdjuster!: the adjuster to use, not null
Return
OffsetTime! an OffsetTime based on this with the adjustment made, not null
Exceptions
java.time.DateTimeException if the adjustment cannot be made
java.lang.ArithmeticException if numeric overflow occurs

with

Added in API level 26
fun with(
    field: TemporalField!,
    newValue: Long
): OffsetTime!

Returns a copy of this time with the specified field set to a new value.

This returns an OffsetTime, based on this one, with the value for the specified field changed. This can be used to change any supported field, such as the hour, minute or second. If it is not possible to set the value, because the field is not supported or for some other reason, an exception is thrown.

If the field is a ChronoField then the adjustment is implemented here.

The OFFSET_SECONDS field will return a time with the specified offset. The local time is unaltered. If the new offset value is outside the valid range then a DateTimeException will be thrown.

The other supported fields will behave as per the matching method on LocalTime#with(TemporalField, long) LocalTime}. In this case, the offset is not part of the calculation and will be unchanged.

All other ChronoField instances will throw an UnsupportedTemporalTypeException.

If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.adjustInto(Temporal, long) passing this as the argument. In this case, the field determines whether and how to adjust the instant.

This instance is immutable and unaffected by this method call.

Parameters
field TemporalField!: the field to set in the result, not null
newValue Long: the new value of the field in the result
Return
OffsetTime! an OffsetTime based on this with the specified field set, not null
Exceptions
java.time.DateTimeException if the field cannot be set
java.time.temporal.UnsupportedTemporalTypeException if the field is not supported
java.lang.ArithmeticException if numeric overflow occurs

withOffsetSameInstant

Added in API level 26
fun withOffsetSameInstant(offset: ZoneOffset!): OffsetTime!

Returns a copy of this OffsetTime with the specified offset ensuring that the result is at the same instant on an implied day.

This method returns an object with the specified ZoneOffset and a LocalTime adjusted by the difference between the two offsets. This will result in the old and new objects representing the same instant on an implied day. This is useful for finding the local time in a different offset. For example, if this time represents 10:30+02:00 and the offset specified is +03:00, then this method will return 11:30+03:00.

To change the offset without adjusting the local time use withOffsetSameLocal.

This instance is immutable and unaffected by this method call.

Parameters
offset ZoneOffset!: the zone offset to change to, not null
Return
OffsetTime! an OffsetTime based on this time with the requested offset, not null

withOffsetSameLocal

Added in API level 26
fun withOffsetSameLocal(offset: ZoneOffset!): OffsetTime!

Returns a copy of this OffsetTime with the specified offset ensuring that the result has the same local time.

This method returns an object with the same LocalTime and the specified ZoneOffset. No calculation is needed or performed. For example, if this time represents 10:30+02:00 and the offset specified is +03:00, then this method will return 10:30+03:00.

To take into account the difference between the offsets, and adjust the time fields, use withOffsetSameInstant.

This instance is immutable and unaffected by this method call.

Parameters
offset ZoneOffset!: the zone offset to change to, not null
Return
OffsetTime! an OffsetTime based on this time with the requested offset, not null

withSecond

java.time.DateTimeException if the second value is invalid

Properties

MAX

Added in API level 26
static val MAX: OffsetTime!

The maximum supported OffsetTime, '23:59:59.999999999-18:00'. This is the time just before midnight at the end of the day in the minimum offset (larger negative offsets are later on the time-line). This combines LocalTime#MAX and ZoneOffset#MIN. This could be used by an application as a "far future" date.

MIN

Added in API level 26
static val MIN: OffsetTime!

The minimum supported OffsetTime, '00:00:00+18:00'. This is the time of midnight at the start of the day in the maximum offset (larger offsets are earlier on the time-line). This combines LocalTime#MIN and ZoneOffset#MAX. This could be used by an application as a "far past" date.
