ical/ics files created by mythweb do not set the time correctly in google calendar, due to TZ issues - patch attached.

[matt@…]

Google Calendar is very picky about the data it will accept from an ICS file provided to it via a URL (i.e. subscribing to a calendar).

The attached patch resolves the issue by converting all times to UTC, and setting the TZID to Etc/Universal?, which Google seems to like.

This seems to be the least invasive means to get the calendar to work correctly with Google. Another method would be the leave out the TZID, and add a "Z" to the end of the UTC time string, but the vcalendar class doesn't seem to support this natively.

Patch to convert ical time information to UTC, and set TZID to Etc/Universal?

Another method would be to use the X-WR-TIMEZONE property of vcalendar. This property is supported by Google calendar, Outlook, and iCal, amongst others I'm sure. The code I put in modules/tv/tmpl/ical/upcoming.php is

$tz = date("e"); $calendar->setProperty( "X-WR-TIMEZONE", $tz );

We've decided not to do a 0.22 point release

Bumping enhancement patch to next release.

(In [24910]) Fixes #7270, this adds in the X-WR-TIMEZONE header by default to all vcalendar outputs

Unfortunately, this doesn't seem to do the trick for Google. They say they need this, but they also need the much more complex VTIMEZONE/TZID/TZOFFSETFROM/TZOFFSETTO... type entries. I think the original approach of utilizing UTC is much more simplistic, and actually works with Google atrocious ICAL parser.
