I have numerous appointments in my calendar. I also do a lot of travelling World Wide. As I arrive in a different time-zone I change the setting on my PC to match the current location. I understand that if I receive a new invitation to an appointment while in the new time-zone then this will appear in my calendar correctly at the current time-zone setting. However I had expected the calendar to update all existing appointments received and accepted from others, to the new time-zone but this does not happen. Is there a facility to make this occur?
