public class Converters {
    @TypeConverter
    public fun fromTimestamp(value: Long): Date {
        return value == null ? null : Date(value)
    }

    @TypeConverter
    public fun dateToTimestamp(date: Date): Long {
        if (date == null) {
            return null
        } else {
            return date.getTime()
        }
    }
}
