email hook datetime exeception on all day event #2037
Description
I spotted that when I have email hook enabled and I'm creating all day event (event with start and end as date without start/end time) I end up with duplicated event once I sync them with DAVx5 from my Android phone.
There I'm attaching log presenting the issue.
