    There is a problem in synchronization when connecting to Horde CalDav.

    Calendars are maitained on Horde, and subscriptions are from both Thunderbird (+Lightning), and DAVDroid.

    • Events created using Phone local calendar, all are sincronized to Horde and without problems to Thunderbird.
    • Events created using Thunderbird or with Horde Web got correctly on server, but can’t be sincronized with Phone

    Errors seem similar to bitfireAT/davdroid#405

    There seems to be an error in the time zone definitions so ical4j throws a NullPointerException.

    Can you please post the .ics contents of such an event?

    On my Android device, there’s no time zone “America/Montevideo”. Can you try another time zone, maybe one that is also present on your Android device? You can try to create an event there and see which time zones are offered.

    TimeZone America/Montevideo is part of the tz database. At least from ical4j documentation i’m assuming it is very well supported.

    Android’s calendar storage doesn’t use ical4j (only DAVdroid does), so it can only process time zones which are known in the Android system.

    Could you please verify that America/Montevideo is not selectable in your calendar app and try a time zone that is present in your Android system?

    The string displayed for the zone in calendar is ‘Uruguay Standard Time’.

    As I understand, ‘America/Montevideo’ is understood by android. It should be very easy to create a program that iterates over TimeZone list printing its Name and/or Ids to verify this.

    DAVdroid logs contain the output of the function that searches through the Android time zones. Could you please provide logs?

    Debug logs went on the first comment, on this gist

    Sorry, didn’t see that. I’m now able to reproduce the issue with our testing device and will have a look.

    Update: Removing the VTIMEZONE definition solves the problem and the event is correctly created in the America/Montevideo timezone, so it’s existing in Android.

    Excellent. I think this other gist is old, but there is already listing android timezone ids and ‘America/Montevideo’ seems to be there.

    It seems like ical4j can’t parse the VTIMEZONE given by Horde. The one bundled with ical4j works.

    Do you know if there’s something like a VTIMEZONE validator out there? Do you think it’s possible that the Horde VTIMEZONE is incorrect or that the problem is caused by ical4j and for what reason?

    VTIMEZONE given by Horde (can’t be parsed by ical4j 1.0.6):

    The problem are the time zone components which don’t have DTSTART, TZOFFSETFROM and TZOFFSETTO, for instance:

    BEGIN:STANDARD
TZOFFSETFROM:-0330
TZOFFSETTO:-0330
TZNAME:UY-T
END:STANDARD

    According to RFC 5545 3.6.5, a standardc time zone component must have a DTSTART value. Such time zone component without DTSTART wouldn’t make any sense because you can’t know when this UY-T time with-0330 offset is defined.

    ical4j expects exactly this (a DTSTART) and throws an exception.

    So, the VTIMEZONE provided by Horde is invalid. I don’t know whether it’s generated by Horde or uploaded by another client and just taken over by Horde.

    Unfortunately, it seems that the issue was not reported to Horde, so it occured again. And it will occur again and again…
