. Bug #79580 (date_create_from_format misses leap year).
. Bug #80974 (Wrong diff between 2 dates in different timezones).
. Bug #81097 (DateTimeZone silently falls back to UTC when providing an offset with seconds).
. Bug #81273 (Date interval calculation not correct).
It fixes several bugs:
- Fixed bug #45554 (Inconsistent behavior of the u format char).
- Fixed bug #48225 (DateTime parser doesn't set microseconds for "now").
- Fixed bug #52514 (microseconds are missing in DateTime class).
- Fixed bug #52519 (microseconds in DateInterval are missing).
- Fixed bug #68506 (General DateTime improvments needed for microseconds to become useful).
- Fixed bug #73109 (timelib_meridian doesn't parse dots correctly).
- Fixed bug #73247 (DateTime constructor does not initialise microseconds property).
It also updates timelib to 2016.04, and updates a data mapping file, which
causes changes to the volatile abbreviations tests.
We need to use the 64bit header for the second set of transitions, as there
could be a different amount of transitions. This also opens up the way towards
real 64bit support.
. support for diffing date/times through date_diff() / DateTime::diff().
. added DateInterval class to represent the difference between two date/times.
. support for parsing ISO intervals for use with DateInterval.
. date_add() / DateTime::add(), date_sub() / DateTime::sub() for applying an
interval to an existing date/time.
