This fixes:
- Fixed bug #72719 (Relative datetime format ignores weekday on sundays only).
- Fixed bug #73294 (DateTime wrong when date string is negative).
- Fixed bug #73489 (wrong timestamp when call setTimeZone multi times with UTC
offset).
- Fixed bug #73858 (first/last day of' flag is not being reset).
- Fixed bug #73942 ($date->modify('Friday this week') doesn't return a Friday
if $date is a Sunday).

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.
Adding a non-zero multiple of 5 weekdays to any Friday, Saturday, or

not suffer from this issue.
. support for diffing date/times through date_diff() / DateTime::diff().
. added DateInterval class to represent the difference between two date/times.

. date_add() / DateTime::add(), date_sub() / DateTime::sub() for applying an
interval to an existing date/time.
