- added standard widget to select timezones
- modified egw_time::server2user and ::user2server to return NULL, if
time can not be parsed, not throwing an exception (as this are legacy
function meant to easy convert existing code, eg. replace strtotime())
only if you select more then one timezone to display in it)
- moved generation of beautified timezone array to egw_time
- moved all preferences hooks to a new class preferences_hooks (updated
version so setup updates hook data, or you need to call admin>>update
hooks)
calendar, plus a first calendar implemenation.
This implementation just replaces following calendar_bo methods:
- date2ts($date,$user2server=False)
- date2array($date,$server2user=False)
- date2string($date,$server2user=False,$format='Ymd')
- format_date($date,$format='')
which static methods from egw_time.
If your server is in same timezone as the user, you should experience no
difference. As a small test, you can switch to an other timezone (eg.
UTC) to recognice on a weekly repeating event (which still repeats on
equal server time!) that it moves by one hour when daylight saving
changes. This switching to a TZ with different daylight saving rules,
was not working before.
Happy testing :-)
