Load iCal assumes local timezone for all events?

I have an icalendar feed which spits everything out as Z time, but it is parsed as local time when loaded into the scheduler 3.0. E.g., the following becomes a multi-day event, but is an early evening event in Indiana.

BEGIN:VEVENT DTSTART;VALUE=DATE-TIME:20120202T230000Z DTEND;VALUE=DATE-TIME:20120203T010000Z UID:2279 DTSTAMP:20120203T154618Z SUMMARY:IUS CSF Meal DESCRIPTION;ENCODING=QUOTED-PRINTABLE:We serve a free meal for the IUS Christian Student Fellowship at the Associ= ation Ministry Center. CATEGORIES:Special Event END:VEVENT
I noticed the samples don’t use any time zone.

you can try to use

scheduler.config.server_utc = true;

The only effect that seems to have is to change my database events to Z time, but the ical events are still Z time. FWIW, I’m pretty sure my server is not set to Z time.

Sorry I misunderstood your original question
Current version of iCal export doesn’t allow to set time zone, we will update this functionality in the next version ( if you need the fix ASAP - contact sales@dhtmlx.com about customization )
