• Minimum PHP version is now 8.2
• The following classes are now final:
  • YearMonthRange

0.8.1 - 2025-11-11

✨ Compatibility improvements

0.1.10 - 2019-03-08

LocalDateRange::getIterator() is now type-hinted as LocalDate[] to allow static code analysis in IDEs.

0.1.9 - 2018-11-14

New method: LocalDate::daysUntil()

This allows to get the number of days between two dates.

0.1.8 - 2018-10-29

New methods to convert objects to native DateTimeImmutable objects:

• LocalDate::toDateTimeImmutable()
• LocalTime::toDateTimeImmutable()
• LocalDateTime::toDateTimeImmutable()
• ZonedDateTime::toDateTimeImmutable()

0.1.7 - 2018-10-18

New methods to convert to native DateTime objects:

• LocalDate::toDateTime()
• LocalTime::toDateTime()
• LocalDateTime::toDateTime()

This makes these methods in line with their fromDateTime() counterparts.

Note: even though these classes represent partial date-time concepts, PHP merges all these concepts into a single DateTime class, so it is relevant to be able to easily export them as native PHP date-times, with sensible defaults.

0.1.6 - 2018-10-18

New method:

ZonedDateTime::toDateTime() : converts the ZonedDateTime to a native DateTime object.

0.1.5 - 2018-10-13

• LocalDateTime::fromDateTime()
• ZonedDateTime::fromDateTime()

0.1.3 - 2018-02-06

This release adds support for YearWeek.

0.1.2 - 2017-10-04

Bug fix:

• Duration::multipliedBy() could return an invalid Duration with negative nanos

New methods:

• Instant::toDecimal() returns a decimal timestamp such as 123456789.123456
• FixedClock::move() allows to move the clock by a number of seconds and/or nanos

New clock implementation:

• ScaleClock makes the time move at a given pace

New feature:

• Methods such as now() now use the clock returned by DefaultClock. By default, this clock is still SystemClock, but it can now be overridden in tests. DefaultClock offers the freeze(), travel() and scale() methods inspired by timecop.

0.1.1 - 2017-10-04

ZonedDateTime::isPast() and isFuture() now accept an optional Clock parameter.

0.1.0 - 2017-10-04

First beta release.
