When entering a parent event in front end, the child events are offset by 1 hour. I'm having to manually go into the back end to edit the child event times.
Infact, It is not a bug in Event Booking, it is just because timezone change one time in a year (I remember that in some countries, when summer (or winter , I don't remember it correctly) comes, the timezone will change 1 hour and that's the reason causing the issue in Event Booking . I am afraid of we cannot do anything in Event Booking for now !
