    The main API for dates, times, instants, and durations.

    The main API for dates, times, instants, and durations.

    The classes defined here represent the principal date-time concepts, including instants, durations, dates, times, time-zones and periods. They are based on the ISO calendar system, which is the de facto world calendar following the proleptic Gregorian rules. All the classes are immutable and thread-safe.

    Each date time instance is composed of fields that are conveniently made available by the APIs. For lower level access to the fields refer to the org.threeten.bp.temporal package. Each class includes support for printing and parsing all manner of dates and times. Refer to the org.threeten.bp.format package for customization options.

    The org.threeten.bp.chrono package contains the calendar neutral API. This is intended for use by applications that need to use localized calendars. It is recommended that applications use the ISO-8601 dates and time classes from this package across system boundaries, such as to the database or across the network. The calendar neutral API should be reserved for interactions with users.

    Dates and Times

    org.threeten.bp.Instant is essentially a numeric timestamp. The current Instant can be retrieved from a org.threeten.bp.Clock. This is useful for logging and persistence of a point in time and has in the past been associated with storing the result from java.lang.System#currentTimeMillis().

    org.threeten.bp.LocalDate stores a date without a time. This stores a date like '2010-12-03' and could be used to store a birthday.

    org.threeten.bp.LocalTime stores a time without a date. This stores a time like '11:30' and could be used to store an opening or closing time.

    org.threeten.bp.LocalDateTime stores a date and time. This stores a date-time like '2010-12-03T11:30'.

    org.threeten.bp.OffsetTime stores a time and offset from UTC without a date. This stores a date like '11:30+01:00'. The ZoneOffset is of the form '+01:00'.

    org.threeten.bp.OffsetDateTime stores a date and time and offset from UTC. This stores a date-time like '2010-12-03T11:30+01:00'. This is sometimes found in XML messages and other forms of persistence, but contains less information than a full time-zone.

    org.threeten.bp.ZonedDateTime stores a date and time with a time-zone. This is useful if you want to perform accurate calculations of dates and times taking into account the org.threeten.bp.ZoneId, such as 'Europe/Paris'. Where possible, it is recommended to use a simpler class. The widespread use of time-zones tends to add considerable complexity to an application.

    Duration and Period

    Beyond dates and times, the API also allows the storage of period and durations of time. A org.threeten.bp.Duration is a simple measure of time along the time-line in nanoseconds. A org.threeten.bp.Period expresses an amount of time in units meaningful to humans, such as years or hours.

    Additional value types

    org.threeten.bp.Year stores a year on its own. This stores a single year in isolation, such as '2010'.

    org.threeten.bp.YearMonth stores a year and month without a day or time. This stores a year and month, such as '2010-12' and could be used for a credit card expiry.

    org.threeten.bp.MonthDay stores a month and day without a year or time. This stores a month and day-of-month, such as '--12-03' and could be used to store an annual event like a birthday without storing the year.

    org.threeten.bp.Month stores a month on its own. This stores a single month-of-year in isolation, such as 'DECEMBER'.

    org.threeten.bp.DayOfWeek stores a day-of-week on its own. This stores a single day-of-week in isolation, such as 'TUESDAY'.

    Support for calendar systems other than the default ISO.

    Support for calendar systems other than the default ISO.

    The main API is based around the calendar system defined in ISO-8601. This package provides support for alternate systems.

    The supported calendar systems includes:

    -Hijrah calendar -Japanese calendar -Minguo calendar -Thai Buddhist calendar

    It is intended that applications use the main API whenever possible, including code to read and write from a persistent data store, such as a database, and to send dates and times across a network. This package is then used at the user interface level to deal with localized input/output. See ChronoLocalDate for a full discussion of the issues.

    Example

    This example creates and uses a date in a non-ISO calendar system.

     // Print the Thai Buddhist date ChronoLocalDate now1 =
ThaiBuddhistChronology.INSTANCE.now(); int day = now1.get(ChronoField.DAY_OF_MONTH); int dow =
now1.get(ChronoField.DAY_OF_WEEK); int month = now1.get(ChronoField.MONTH_OF_YEAR); int year =
now1.get(ChronoField.YEAR); System.out.printf(" Today is %s %s %d-%s-%d%n",
now1.getChronology().getId(), dow, day, month, year);

// Enumerate the list of available calendars and print today for each Set<String> names =
Chronology.getAvailableIds(); for (String name : names) { Chronology<?> chrono =
Chronology.of(name); ChronoLocalDate<?> date = chrono.now(); System.out.printf(" %20s:
%s%n", chrono.getId(), date.toString()); }

// Print today's date and the last day of the year for the Thai Buddhist Calendar.
ChronoLocalDate first = now1 .with(ChronoField.DAY_OF_MONTH, 1) .with(ChronoField.MONTH_OF_YEAR,
1); ChronoLocalDate last = first .plus(1, ChronoUnit.YEARS) .minus(1, ChronoUnit.DAYS);
System.out.printf(" %s: 1st of year: %s; end of year: %s%n", last.getChronology().getId(), first,
last);

  9. def from(temporal: TemporalAccessor): MinguoDate

    Obtains a MinguoDate from a temporal object.

    Obtains a MinguoDate from a temporal object.

    This obtains a date in the Minguo calendar system based on the specified temporal. A TemporalAccessor represents an arbitrary set of date and time information, which this factory converts to an instance of MinguoDate.

    The conversion typically uses the EPOCH_DAY field, which is standardized across calendar systems.

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

    temporal

    the temporal object to convert, not null

    returns

    the date in Minguo calendar system, not null

    Exceptions thrown

    DateTimeException if unable to convert to a { @code MinguoDate}

  16. def now(clock: Clock): MinguoDate

    Obtains the current MinguoDate from the specified clock.

    Obtains the current MinguoDate from the specified clock.

    This will query the specified clock to obtain the current date - today. Using this method allows the use of an alternate clock for testing. The alternate clock may be introduced using dependency injection.

    clock

    the clock to use, not null

    returns

    the current date, not null

    Exceptions thrown

    DateTimeException if the current date cannot be obtained

  17. def now(zone: ZoneId): MinguoDate

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

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

    This will query the system clock to obtain the current date. Specifying the time-zone avoids dependence on the default time-zone.

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

    zone

    the zone ID to use, not null

    returns

    the current date using the system clock, not null

  18. def now: MinguoDate

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

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

    This will query the system clock in the default time-zone to obtain the current date.

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

    returns

    the current date using the system clock and default time-zone, not null

  19. def of(prolepticYear: Int, month: Int, dayOfMonth: Int): MinguoDate

    Obtains a MinguoDate representing a date in the Minguo calendar system from the proleptic-year, month-of-year and day-of-month fields.

    Obtains a MinguoDate representing a date in the Minguo calendar system from the proleptic-year, month-of-year and day-of-month fields.

    This returns a MinguoDate with the specified fields. The day must be valid for the year and month, otherwise an exception will be thrown.

    prolepticYear

    the Minguo proleptic-year

    month

    the Minguo month-of-year, from 1 to 12

    dayOfMonth

    the Minguo day-of-month, from 1 to 31

    returns

    the date in Minguo calendar system, not null

    Exceptions thrown

    DateTimeException if the value of any field is out of range, or if the day-of-month is invalid for the month-year
