thank you, it works
End time is not used for repeating events
I created a repeating event from 12h00 to 14h00 for 5 consecutive days on my DAViCAl server.
On Android the events are displayed as if they were a 0 minute event from 12h00 to 12h00. The 2h duration is lost.
A single event is correctly synced by not a repeating one.
Thanks for your report. We forgot to write received DURATIONs into the database in the last commit. For further discussion, please see issue #60.
