Update 2016-07-25 - Force date_due to UTC to avoid problematic timezone info like this: DTSTART:TZID=Europe/Zurich:20160724T235900

From https://metacpan.org/pod/DateTime::Format::ICal: "The iCal spec requires that datetimes be formatted either as floating times (no time zone), UTC (with a 'Z' suffix) or with a time zone id at the beginning ('TZID=America/Chicago;...'). If this method is asked to format a DateTime object that has an offset-only time zone, then the object will be converted to

I am not sure this is correct. the UTC time zone internally before formatting." So the TZID should be handled correctly by Thunderbird (I did not try). I think we should either use a floating TZ or the tz returned by C4::Context->tz, but not arbitrarily set it to UTC -- You are receiving this mail because: You are the QA Contact for the bug.
