Alarms are triggering an hour early in version 5

I am using version 5 RC#2 and my alarms are triggering an hour early, i.e. if I have a meeting at 19:30 and I have put a 3 hour warning on the meeting it gets triggered at 15:30 and not 16:30

Hello,
I was unable to simulate the issue. Please send me the problematic event saved as .ics. Thank you.
