It happens often that some timezone is renamed, split, added to the
IANAs list of timezones (that, for PHP is kept updated by the
php-timezonedb PECL extension).
When the information coming from the extension changes, all the
PHPUnit jobs in the world start failing (that's when CIs update
their PHP images, when devs update their packages, ...).
So, what we are doing here is to move that test that check for
every single string existing to be run only when PHPUNIT_LONGTEST
is enabled. That way only places running all tests will run that
one. And every other run just will skip it.
This corresponds to point 1 & 2 of the issue, lower impact in general
and, still be able to enable the tests to run.
The value Etc/GMT-14 was added to the list of known timezones,
and Etc/GMT+13 & Etc/GMT+14 were removed as they are not valid.
Tests were added to ensure that legacy user timezones are mapped
to known timezones. Other tests were changed to reflect the changes
with regards to Etc/GMT+13 and +-14.
Norfolk Island's standard time (NFT) was on UTC+11:30 until 4 October
2015, when it was changed to UTC+11:00. So it's not suitable for 11.5
bad mapping replacement anymore.
It seems that there isn't any other location using such 11.5 timezone
so completely getting rid of it for conversions.
This patch replaces all homegrown timezone
stuff with standard PHP date/time code.
The main change is the introduction of core_date
class that returns normalised user and server
timezones. From now on nobody should be using
$CFG->timezone or $user->timezone directly!
Other new features and fixes:
* admins are prompted for timezone during install
* editing of other users is finally fixed
* timezones are displayed in user profile
* new $this->setTimezone() in phpunit
* time locale is now automatically reset in phpunit
* timezone is now automatically reset in phpunit
* phpunit has Australia/Perth as default timezone
