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 :-)
