I was finally invited to a wedding but when reading the invitation since in Italy we usually say 21:00 insted of 9:00 PM I assumed the time was written there automatically based on the booking time and therefore Server Time. It wasn't. It was Local Time so I was 2 hours late. So a Local Time near it would have been nice. I know there's space for LT at least though I wouldn't even know what that means if I hadn't missed other things due to not knowing Server Time exists.
