The Scheduler works with an idealized continuous timezone.
- Continuous = Unlike most local timezones it doesn't have daylight saving time, so there are no unexpected breaks.
- Idealized = This timezone behaves like GMT and it uses GMT timezone internally but in a typical setup you will pretend that this is your local timezone. And ignore the fact that it is incorrect for events that span over the DST change date.
It is recommended to use date/time formats without the time zone specifier (already converted to the target time zone). See also DayPilot.Date constructor.
