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...
