Multi-day events are split up with overlapping dates when exported as ics, particularly when timezone changes. At least for exporting to Thunderbird, it seems to be fixed with the following in kronolith/lib/Api.php: 828c828 < $events = $kronolith_driver->listEvents(null, null, false, false, false, true, true, true); --- $events = $kronolith_driver->listEvents(null, null, false, false, false, false, true, true);

Multi-day events are split up with overlapping dates when exported as ics, particularly when timezone changes. Here is an event exported from Kronolith 2.2: BEGIN:VEVENT DTSTART:20110413T002500Z DTEND:20110416T022500Z DTSTAMP:20110427T220529Z UID:20110306165810.673097ek81pfc0ow@zzz.com CREATED:20110306T225810Z LAST-MODIFIED:20110426T231601Z SUMMARY:Philadelphia ORGANIZER;CN=Xxx Yyy:mailto:xxx.yyy@zzz.com DESCRIPTION: CATEGORIES: CLASS:PUBLIC STATUS:CONFIRMED TRANSP:OPAQUE END:VEVENT The following is from the same event exported using 3.0.2-git. Note that the last VEVENT starts at 20110415T140000Z, which overlaps with the all-day event before it (depending on which timezone the event is viewed in). Furthermore, the fact that all the events are exported with the same UID seems to cause Thunderbird/Lightning to ignore subsequent duplicates (i.e. the end result is that it displays only the first of the VEVENTs).
