Description Robert Jennings 2006-04-04 14:33:54 UTC
Distribution: Ubuntu 5.10 (breezy)
Package: Evolution
Severity: Normal

Gnome-Distributor: Ubuntu
Synopsis: Recurring meetings set before DST are off by one hour after DST adjustment

Bugzilla-Component: Calendar
Bugzilla-Version: 2.4.x
Description:
Description of Problem:
For meetings scheduled before daylight savings time (before April 2)
that are recurring and continue after daylight savings time has taken
affect the meeting times are off by one hour.

Steps to reproduce the problem:
1. Prior to DST accept a meeting invite like one for a meeting occuring
at 8:00 - 8:30 AM CST.

BEGIN:VCALENDAR

SUMMARY:<SNIP>
DESCRIPTION:
 <SNIP>
RRULE:FREQ=DAILY;INTERVAL=1;UNTIL=20060410T000000Z

ATTENDEE;RSVP=TRUE;ROLE=REQ-PARTICIPANT;CN=<SNIP>;

END:VEVENT
END:VCALENDAR

2. Set system calendar forward to a date after daylight savings took
effect, meeting will now occur at 9:00 - 9:30 AM in the local timezone.


Actual Results:
Calendar entries are 1 hour off.

Expected Results:
Calendar entries do not shift 1 hour.

How often does this happen?
Half of my calendar entries are like this.  I will probably need to drop
evolution for corporate use because I can't affort to miss meetings
because I thought they were happening an hour later than they really
are.

Attaching a portion of calendar.ics from the system.  There are two timezone stanzas and the calendar entry in question.  The calendar entry does not base it's time from a timezone, it uses GMT.  On the day the invite was sent the time offset was correct; 8:00 AM CST was 6 hours later than GMT and meetings were correct.  Now after daylight savings 14:00 GMT is being mapped to 9:00 AM CST using the definition of (GMT-5).
