I live in Moscow. And use timezone Europe/Moscow. When I sync owncloud to android over davdroid - it’s all OK! But if I sync android to owncloud - event will make with Moscow time plus one hour. I tried with other app - all ok.
Please see #3 for extensive discussion. At the moment, accepting invalid certificates is not a priority task.
Thanks for reporting the issue. This is probably a duplicate of #186, please follow up there.
I have just tried with our mailbox.org test account and I can’t reproduce that problem.
Are you sure that you didn’t change the data on the server in the time before DAVdroid uploads the contact? In this case, it would be a conflict and the server VCard would be preferred.
Also, please provide steps to reproduce, debug info and verbose logs.
