Support for calendar systems other than the default ISO.
Provides classes to print and parse dates and times.
Access to date and time using fields and units.
Support for time-zones and their rules.
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.temporalpackage. Each class includes support for printing and parsing all manner of dates and times. Refer to theorg.threeten.bp.formatpackage for customization options.The
org.threeten.bp.chronopackage 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.Instantis essentially a numeric timestamp. The current Instant can be retrieved from aorg.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 fromjava.lang.System#currentTimeMillis().org.threeten.bp.LocalDatestores a date without a time. This stores a date like '2010-12-03' and could be used to store a birthday.org.threeten.bp.LocalTimestores 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.LocalDateTimestores a date and time. This stores a date-time like '2010-12-03T11:30'.org.threeten.bp.OffsetTimestores a time and offset from UTC without a date. This stores a date like '11:30+01:00'. Theorg.threeten.bp.ZoneOffset ZoneOffsetis of the form '+01:00'.org.threeten.bp.OffsetDateTimestores 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.ZonedDateTimestores 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 theorg.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.Durationis a simple measure of time along the time-line in nanoseconds. Aorg.threeten.bp.Periodexpresses an amount of time in units meaningful to humans, such as years or hours.Additional value types
org.threeten.bp.Yearstores a year on its own. This stores a single year in isolation, such as '2010'.org.threeten.bp.YearMonthstores 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.MonthDaystores 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.Monthstores a month on its own. This stores a single month-of-year in isolation, such as 'DECEMBER'.org.threeten.bp.DayOfWeekstores a day-of-week on its own. This stores a single day-of-week in isolation, such as 'TUESDAY'.
