No, the difference varies -- Daylight Savings started on March 13 in the US but on March 27 in the EU, and in that period there was a five hour difference. And: DTSTART;TZID="America/New_York":20220317T100000 DTEND;TZID="America/New_York":20220317T103000 This was in the middle of that period. So this seems like it's working as it should? But if I'm reading the ical file right, this is a recurring (weekly?) event, so it should be at 4pm after March 27... -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
