Thu, 09 Apr 2026 21:18:35 +0000 https://bugs.horde.org/ticket/7628 Timezone problem on sync with synthesis I just installed the synthesis demo version on a windows mobile 6.1 PDA trying to sync with horde. When I try to sync with kronolith the times of the appointments are wrong by one hour. Some background info: - The timezone on the PDA is set to "GMT+1 Berlin,Rom" - The timezone on the server is set to "Europe/Berlin" - The timezone in the horde options (under "Locale and Time") is set to "Europe/Berlin" Bug occurs when: - I add an appointment on the PDA from 10:00-11:00, sync it, it becomes 11:00-12:00 in Horde. - I add an appointment in Horde from 10:00-11:00, sync it, it becomes 09:00-10:00 on the PDA. Horde is the snapshot from http://ftp.horde.org/pub/snaps/2008-11-01/horde-HEAD-2008-11-01.tar.gz and Kronolith same directory, same date: kronolith-HEAD-2008-11-01.tar.gz Sun, 02 Nov 2008 00:48:56 +0000 https://bugs.horde.org/ticket/7628#t50253 Please read http://wiki.horde.org/SyncMLProblemReport and follow the steps to generate complete SyncML debugging information. Thu, 06 Nov 2008 08:38:22 +0000 https://bugs.horde.org/ticket/7628#t50387 Are you sure that you sent me exactly the log from your example below? The log show the following event coming from the client: BEGIN:VCALENDAR VERSION:1.0 BEGIN:VEVENT SUMMARY:Test CLASS:PUBLIC DESCRIPTION: DTSTART:20081106T110000Z DTEND:20081106T120000Z TRANSP:0 AALARM:20081106T104500Z;;;Test DALARM:20081106T104500Z;;;Test END:VEVENT END:VCALENDAR The event is from 11:00-12:00 UTC, which would be 12:00-13:00 GMT+1/Berlin. This doesn't match either the event time on your PDA, nor in Horde. And how did you set up Kronolith? To store events in UTC or in the local timezone?

I have tried it again by changing the time to something different, sync, then changing it back to 12:00-13:00, sync again and it still shows up as 13:00-14:00 while the /tmp/sync/data.txt reads: DTSTART:20081106T110000Z DTEND:20081106T120000Z Kronolith conf.php reads: $conf['calendar']['params']['utc'] = true; > Are you sure that you sent me exactly the log from your example > below?

Thu, 06 Nov 2008 11:28:25 +0000 https://bugs.horde.org/ticket/7628#t50395 Changing the parameter in conf.php to $conf['calendar']['params']['utc'] = false; syncs correctly. So I think there is some localtime converting even when times are stored in UTC somewhere in the code. Thu, 06 Nov 2008 12:03:36 +0000 https://bugs.horde.org/ticket/7628#t50396 I can't reproduce this. This event correctly creates a start time at 12:00 CET when importing with the current git code.
