    Hey,

    Using DAVdroid/1.10.1.1-gplay, editing or creating a recurring event makes all occurrences an all-day event. I tried daily, weekly and monthly events with 10 repetitions. While editing I chose to apply to all occurrences. Editing a single occurrence later also does not work and makes it an all-day event too.

    How to reproduce

    1. Create an event
    2. The local calendar app shows it correctly
    3. Sync
    4. The event is uploaded and the local calendar is updated with an all-day event replacing the exact time of day you have specified

    The following is what gets uploaded for a weekly recurring event on wednesday from 8-9 o’clock:

    PUT /path/to/event.ics HTTP/1.1

    Hello,

    @marki said in Creating/editing a recurring event makes it an all-day event.:

    Using DAVdroid/1.10.1.1-gplay, editing or creating a recurring event makes all occurrences an all-day event. I tried daily, weekly and monthly events with 10 repetitions. While editing I chose to apply to all occurrences. Editing a single occurrence later also does not work and makes it an all-day event too.

    How to reproduce

    1. Create an event
    2. The local calendar app shows it correctly
    3. Sync
    4. The event is uploaded and the local calendar is updated with an all-day event replacing the exact time of day you have specified

    Is it possible that the server doesn’t understand the event and converts it to an all-day event? The event which is uploaded by DAVdroid looks fine:

    DTSTART;TZID=Europe/Luxembourg:20180321T080000

    Event start time: 21 Mar 2018 08:00:00 Europe/Luxembourg

    DURATION:PT3600S

    Event duration: one hour

    RRULE:FREQ=WEEKLY;WKST=MO;COUNT=10;INTERVAL=1;BYDAY=WE

    Every Wednesday, 10 times.

    Trying the same thing in Thunderbird/Lightning looks more reasonable:

    Why?

    PRODID:-//Mozilla.org/NONSGML Mozilla Calendar V1.1//EN
    BEGIN:VEVENT
    RRULE:FREQ=WEEKLY;UNTIL=20180418;BYDAY=WE

    Every Wednesday until 18 Mar 2018

    DTSTART;TZID=Europe/Berlin:20180307T100000

    Event start time: 7 Mar 2018 10:00:00 Europe/Berlin

    DTEND;TZID=Europe/Berlin:20180307T110000

    Event end time: 11:00

    I don’t see anything wrong here. My guess is that the server rewrites the event to an all-day event, maybe because of the Europe/Luxembourg time zone. Why you can try:

    1. After /path/to/event.ics has been put to the server, have a look at what you GET from the server. Is it still correct or is it an all-day event?

    2. Try another timezone on your Android device. For instance, use Europe/Berlin for a certain event and see whether the problem occurs for this event, too.

    3. If this doesn’t help, send the whole sync logs to play@bitfire.at.

    Why?

    Yeah, I was confused by the whole definition of the timezone being included in the event (1916, 1917 etc.), my mistake.

    Indeed looking at what is returned from the server after sync is something like this:

    Clearly, the time is missing.
    I’ll open a ticket with the server vendor.

    Cheers.
