[icalendar-dev] How to specify a UTC offset

[Thomas E. Deutsch]

Hello

I've created following script, to merge multiple iCals into one. But
I've a problem. I need to specify a UTC offset, 'cause Sundbird has
problems mit some of the events without it. Can someone give me a hint
how to do this?

Oh, and if you see another thing I've forgot, feel free to tell me :)

Thanks,

Thomas

from icalendar import Calendar, Event, Timezone

newcal = Calendar()

newcal.add('version', '2.0')
newcal.add('x-wr-calname', CALENDARNAME)
newcal.add('X-WR-TIMEZONE', 'Europe/Zurich')

newtimezone = Timezone()
newtimezone.add('tzid', "Europe/Zurich")
newcal.add_component(newtimezone)

for s in glob.glob(CALDIR + '*.ics'):

      calfile = open(s,'rb')
      cal = Calendar.from_string(calfile.read())
      for component in cal.subcomponents:
         if component.name == 'VEVENT':
            newcal.add_component(component)
      calfile.close()
