You can set Calendar to view your or another calendar's appointments in a time zone other than your local one.
Choose Time Zone from the View menu.
Choose the Custom Time setting.
In the Hours field, edit the number of hours before or after Greenwich Mean Time that you want your calendar set to.
For example, to synchronize your calendar for Pacific Standard Time, choose GMT+8 hours. For Finland, choose GMT-2 hours. For Japan, choose GMT-9 hours. You may have to adjust by one hour for daylight, or summer, time.
To revert to your own time zone, click the My Time setting in the Time Zone dialog box.
Click OK to apply changes and close the dialog box.
