when I change the start-time in an calendar item in a synced calendar the time changes (after sync to the Server) exactly one hour. I tried the old DAVdrouid-Version 0.8.2. Here it didn’t happen and everything works fine.
At the Server side runs Horde 5.2.7 with kronolith 4.2.9.
On my Smarthone runs CyanogenMod 12.1 with DAVdroid 0.9.1.3.
There are no errors/warnings/infos according to this problem in Horde/Apache log or messages on the phone.
Maybe it is a timezone or daylight-saving-time issue similar to this:
I think it may be reproduceable without Horde too.
Can you please help?
