@memphismark thanks for the cal entries…
the ‘problem’ is the time in the cal entries…
according to the ICAL spec
IF the timezone is specified (yes) then the CLOCK value MUST BE UTC time.
but these entries don’t have Z on the end…
so its confusing
without the Z the cal entries are on the 19th, but sat is the 20th.
add the Z on the end of the clock and it works correctly
