For those traveling or in AZ, it is useful to know how-to change the time zone in Outlook Web Access (OWA). The following tip contains a walk-through to that ends. It is important that your Windows time zone (as shown in the previous tip) and your OWA tie match.
Sign into Outlook Web Access and click on Options.

Once in Options scroll down to the section that says DATE AND TIME FORMATS
Change the Time Zone to one that you need, and at the top click on Save and Close.

That should make the change to your calendar.
