|Summary||0000763: All-day events shown as two days on DST start date|
An all-day event on the day when daylight savings time starts is shown on both the correct and also the next day in the web calendar.
When viewing in many European time zones, e.g. Berlin, the following entry will show on both March 27 and March 28, 2011:
|Tags||No tags attached.|
Does this happen with events generated from SOGo web, and from Lightning?
The events above are generated by project24.info, a popular online generator for (bank etc.) holiday ICS files, which can be subscribed to:
No, events generated in the SOGo web interface:
However, all but the SOGo web interface also display the first entry as a single day only, including Lightning.
It seems that the SOGo web interface is the only one interpreting DTSTART;VALUE=DATE without DTEND as 24 hours instead of one day (which is only 23 hours on DST start), as mandated by RFC 5545 ("For cases where a "VEVENT" calendar component specifies a "DTSTART" property with a DATE value type but no "DTEND" nor "DURATION" property, the event's duration is taken to be one day.").
If the problem only occurred during the import and would disappear after the first edit, I would not bother too much. However, this type of calendar is subscribed to, so local editing is not an option.
Does that still happen with v1.3.3?
It still happens on our 1.3.3 installation; I cannot verify with the SOGo demo, as its Calendar module is currently defunct (see mail to sogo-users)
BTW: To test on SOGo demo once its calendar works again, subscribe to http://www.project24.info/feiertageics.php?path=AAAAA/AAAA/JAA/N/0/5231fc59371c6e8d40fceacda70fb5c3 and go to March 27/28, 2011
Also still persists in sogo-demo.inverse.ca
