    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'.

  • package chrono

    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);

  • package format

    Provides classes to print and parse dates and times.

    Provides classes to print and parse dates and times.

    Printing and parsing is based around the DateTimeFormatter class. That class contains common formatters and factory methods. The DateTimeFormatterBuilder class is available for advanced and complex use cases.

    Localization occurs by calling withLocale(Locale) on the formatter. Further customization is possible using DecimalStyle.

  • package temporal

    Access to date and time using fields and units.

    Access to date and time using fields and units.

    This package expands on the base package to provide additional functionality for more powerful use cases. Support is included for:

    • Units of date-time, such as years, months, days and hours
    • Fields of date-time, such as month-of-year, day-of-week or hour-of-day
    • Date-time adjustment functions
    • Different definitions of weeks

    Fields and Units

    Dates and times are expressed in terms of fields and units. A unit is used to measure an amount of time, such as years, days or minutes. All units implement org.threeten.bp.temporal.TemporalUnit. The set of well known units is defined in org.threeten.bp.temporal.ChronoUnit, for example, org.threeten.bp.temporal.ChronoUnit#DAYS. The unit interface is designed to allow applications to add their own units.

    A field is used to express part of a larger date-time, such as year, month-of-year or second-of-minute. All fields implement org.threeten.bp.temporal.TemporalField. The set of well known fields are defined in org.threeten.bp.temporal.ChronoField, for example, org.threeten.bp.temporal.ChronoField#HOUR_OF_DAY. An additional fields are defined by org.threeten.bp.temporal.JulianFields. The field interface is designed to allow applications to add their own fields.

    This package provides tools that allow the units and fields of date and time to be accessed in a general way most suited for frameworks. org.threeten.bp.temporal.Temporal provides the abstraction for date time types that support fields. Its methods support getting the value of a field, creating a new date time with the value of a field modified, and extracting another date time type, typically used to extract the offset or time-zone.

    One use of fields in application code is to retrieve fields for which there is no convenience method. For example, getting the day-of-month is common enough that there is a method on LocalDate called getDayOfMonth(). However for more unusual fields it is necessary to use the field. For example, date.get(ChronoField.ALIGNED_WEEK_OF_MONTH). The fields also provide access to the range of valid values.

    Adjustment

    A key part of the date-time problem space is adjusting a date to a new, related value, such as the "last day of the month", or "next Wednesday". These are modeled as functions that adjust a base date-time. The functions implement org.threeten.bp.temporal.TemporalAdjuster and operate on org.threeten.bp.temporal.Temporal. A set of common functions are provided in org.threeten.bp.temporal.TemporalAdjusters. For example, to find the first occurrence of a day-of-week after a given date, use org.threeten.bp.temporal.TemporalAdjusters#next(DayOfWeek), such as date.with(next(MONDAY)).

    Weeks

    Different locales have different definitions of the week. For example, in Europe the week typically starts on a Monday, while in the US it starts on a Sunday. The org.threeten.bp.temporal.WeekFields class models this distinction.

    The ISO calendar system defines an additional week-based division of years. This defines a year based on whole Monday to Monday weeks. This is modeled in org.threeten.bp.temporal.IsoFields.

  4. val MAX: OffsetDateTime

    The maximum supported OffsetDateTime, '+999999999-12-31T23:59:59.999999999-18:00'.

    The maximum supported OffsetDateTime, '+999999999-12-31T23:59:59.999999999-18:00'. This is the local date-time just before midnight at the end of the maximum date in the minimum offset (larger negative offsets are later on the time-line). This combines LocalDateTime#MAX and ZoneOffset#MIN. This could be used by an application as a "far future" date-time.

  5. val MIN: OffsetDateTime

    The minimum supported OffsetDateTime, '-999999999-01-01T00:00:00+18:00'.

    The minimum supported OffsetDateTime, '-999999999-01-01T00:00:00+18:00'. This is the local date-time of midnight at the start of the minimum date in the maximum offset (larger offsets are earlier on the time-line). This combines LocalDateTime#MIN and ZoneOffset#MAX. This could be used by an application as a "far past" date-time.

  11. def from(temporal: TemporalAccessor): OffsetDateTime

    Obtains an instance of OffsetDateTime from a temporal object.

    Obtains an instance of OffsetDateTime from a temporal object.

    A TemporalAccessor represents some form of date and time information. This factory converts the arbitrary temporal object to an instance of OffsetDateTime.

    The conversion extracts and combines LocalDateTime and ZoneOffset. If that fails it will try to extract and combine Instant and ZoneOffset.

    This method matches the signature of the functional interface TemporalQuery allowing it to be used in queries via method reference, OffsetDateTime::from.

    returns

    the offset date-time, not null

    Exceptions thrown

  18. def now(clock: Clock): OffsetDateTime

    Obtains the current date-time from the specified clock.

    Obtains the current date-time from the specified clock.

    This will query the specified clock to obtain the current date-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.

    clock

    the clock to use, not null

    returns

    the current date-time, not null

  19. def now(zone: ZoneId): OffsetDateTime

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

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

    This will query the system clock to obtain the current date-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.

    zone

    the zone ID to use, not null

    returns

    the current date-time using the system clock, not null

  20. def now: OffsetDateTime

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

    Obtains the current date-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 date-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.

    returns

  21. def of(year: Int, month: Int, dayOfMonth: Int, hour: Int, minute: Int, second: Int, nanoOfSecond: Int, offset: ZoneOffset): OffsetDateTime

    Obtains an instance of OffsetDateTime from a year, month, day, hour, minute, second, nanosecond and offset.

    Obtains an instance of OffsetDateTime from a year, month, day, hour, minute, second, nanosecond and offset.

    This creates an offset date-time with the seven specified fields.

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

    year

    the year to represent, from MIN_YEAR to MAX_YEAR

    month

    the month-of-year to represent, from 1 (January) to 12 (December)
