A recurring event whose DTSTART is written in UTC ("...Z", as a JMAP
timeZone of Etc/UTC is stored) came back in the zone of the request:
read with America/Phoenix, an 18:00 UTC weekly event said 01:00Z and,
for its occurrences, America/Phoenix. Named-zone and floating series and
one-off events were right.
calcard took a component's start zone from its TZID or the default, and
the server's default is floating, so every instance of a UTC rule was
stored floating and read in the request's zone. The DTSTART's own
offset now wins, as in calcard 0.4. Series already stored floating are
read in their DTSTART's offset when it has one, so no reindex is needed.
Occurrences of a UTC series are labeled Etc/UTC like the base event, and
the base event's utcStart is worked out before the event is taken out of
its data.
Fixes #303.
