getTimeZoneDatabaseVersion
public static String getTimeZoneDatabaseVersion ()
Returns a String indicating the version of the time zone database currently in use. The format of the string is dependent on the underlying time zone database implementation, but will typically contain the year in which the database was updated plus a letter from a to z indicating changes made within that year.
Time zone database updates should be expected to occur periodically due to political and legal changes that cannot be anticipated in advance. Therefore, when computing the time for a future event, applications should be aware that the results may differ following a time zone database update. This method allows applications to detect that a database change has occurred, and to recalculate any cached times accordingly.
The time zone database may be assumed to change only when the device runtime is restarted. Therefore, it is not necessary to re-query the database version during the lifetime of an activity.

---|---|
String |
getTimeZoneIdsForCountryCode
public static List<String> getTimeZoneIdsForCountryCode (String countryCode)
Returns time zone IDs for time zones known to be associated with a country.
The list returned may be different from other on-device sources like
TimeZone.getRegion(String)
as it can be curated to avoid
contentious or obsolete mappings.
Parameters | |
---|---|
countryCode |
String : the ISO 3166-1 alpha-2 code for the country as can be obtained using
Locale.getCountry()
This value cannot be null . |
Returns | |
---|---|
List<String> |
IDs that can be passed to TimeZone.getTimeZone(String) or similar
methods, or null if the countryCode is unrecognized |
isTimeBetween
public static boolean isTimeBetween (LocalTime reference, LocalTime start, LocalTime end)
This method is used to find if a clock time is inclusively between two other clock times
Parameters | |
---|---|
reference |
LocalTime : The time of the day we want check if it is between start and end
This value cannot be null . |
start |
LocalTime : The start time reference
This value cannot be null . |
end |
LocalTime : The end time
This value cannot be null . |
Returns | |
---|---|
boolean |
true if the reference time is between the two clock times, and false otherwise. |
