It looks as though libical1 may be the culprit.
I installed libical0 and removed libical1. A test event synced correctly.
Then replaced libical0 with libical1 and synced a second test event. The
error occurred with this one.
The logs that Jane sent me show a major difference between libical0 and
libical1: libical1 includes information about historic summer saving
times. This seems to break the mapping of CalDAV even timezones to
internal timezones extracted from libical such that the phone gets an
event in New_Zealand timezone (probably from libsynthesis itself) with
outdated information (?).
I still need to dig deeper into this to determine why the libical
information is no longer used.
