Outlook calendar import question

A new employee at my company wants to import contact and calendar data from his previous computer. The old computer was running Outlook 2000 on Eastern time and the new one is running Outlook 2003 on Pacific time. He exported his contact records which contained birthdays for everyone. When he imported them to Outlook, the birthdays are shown on the previous day. Apparently the birthdays were recorded as occuring at midnight on the day of the birthday and when he imported them to a computer running Pacific time, the events moved to 9pm on the previous day. Is there any way to fix this?
