How can I add a second time zone to the Outlook for Mac calendar?

Thanks
Marcus
how do i change the actual time(clock) to correct zone !!!!!!
I am in the Eastern time zone but my received and sent emails are posting central time zone values
An email I receive at 4pm is coming in saying I received it at 4am. ie seems to be UK time instead of New Zealand time. I have my hotmail calendar time zone set up as Auckland/Wellington so why are emails still coming through with the wrong times on?
