SYMPTOMS

In Outlook, you can display two separate time zones in the Calendar. This allows you to see your local time zone and the time zone of a city that you often travel to. When you travel to that other time zone, you can use the Swap Time Zones option to change the position of the time bar in the Calendar. Using the Swap Time Zones option in Outlook 2010 results in unexpected behavior.

Consider the following scenario. You are in a time zone that does not observe Daylight Saving Time (DST). You switch Outlook from this DST time zone to a time zone that supports DST and the current date is within the observed DST. You see the times in the Calendar time zone bars are off by one hour. Additionally, the Date and Time Control Panel applet in Windows does not have the Automatically adjust clock for Daylight Saving Time checkbox enabled.

CAUSE

The option to swap time zones in Outlook does not base the DST setting on the new time zone.
