Fri, 10 Apr 2026 01:05:03 +0000 https://bugs.horde.org/ticket/8355 non-standardconform iCal-File An example .ics-file is attached. When syncing this file, generated by Horde Groupware Edition 1.2.3, to lightning, the event is repeated 4 times, not the expected 5 times. This is due to an non-standardconform iCal-File, as we discussed a bit earlier in the bugtracker of lightning: https://bugzilla.mozilla.org/show_bug.cgi?id=498621 Has somebody a solution for this bogus behavior? Which files/functions are affected? Wed, 17 Jun 2009 14:17:09 +0000 https://bugs.horde.org/ticket/8355#t54621 > Has somebody a solution for this bogus behavior? > Which files/functions are affected? I have found the file, creating the iCal recurrence rule in HORDE_BASE/kronolith/lib/Recurrence.php (Horde Groupware Edition 1.2.3) ca. in line 1061 the function toRRule20(...) is defined. I changed the code to the following, which works fine for me: function toRRule20($calendar) { ... if ($this->hasRecurEnd()) { #$rrule .= ';UNTIL=' . $calendar->_exportDate($this->recurEnd); #doesn't sync correctly with lightning 0.9 $rrule .= ';UNTIL=' . $calendar->_exportDateTime($this->recurEnd); #works } ... } But the origin of the time is a mysterium to me. Maybe someone really knows how to solve this problem completely in a neat way. Wed, 17 Jun 2009 15:54:45 +0000 https://bugs.horde.org/ticket/8355#t54625 Duplicate of bug #7846.
