Some more information on my (probably) timezone error. I created an
event externally and invited myself. The ICS file is right and using the
ICS Inspector t-bird plugin, I can view the ICS file as it is reported
to t-bird by SOGo. The file looks correct and is shown below (I've
removed some lines that aren't relevant)
BEGIN:VTIMEZONE
TZID:America/Denver
BEGIN:DAYLIGHT
TZOFFSETFROM:-0700
TZOFFSETTO:-0600
TZNAME:MDT
DTSTART:19700308T020000
RRULE:FREQ=YEARLY;BYDAY=2SU;BYMONTH=3
END:DAYLIGHT
BEGIN:STANDARD
TZOFFSETFROM:-0600
TZOFFSETTO:-0700

END:STANDARD
END:VTIMEZONE

END:VCALENDAR
The event is on Jan 22nd at 12:00 America/Denver time, where that
timezone is defined as -0700 by the TIMEZONE section (Jan is between Nov
and March, and thus Standard time). Everything looks good here. But the
event shows up in SOGo webmail at "11:00 MST" If I change my timezone
preferences in SOGo to Chicago timezone, the event shows up at "12:00
CST" so it is doing the adjustments for timezone, but somehow is reading
the time wrong for the ICS file.
Is there a way to get more information on why SOGo web views the event
as being at 11 and not 12? Any other ideas of things to check / change
or report?

could this be similar to
