Calendar doesn't transfer right when moving pst file

[mackconsult]

I have outlook 2003 installed at home and at my office. I take a pst file and transfer it to a thumb drive to transfer outlook information from home to work. Just built a new workstation at home and know outlook acts very strange.

The calendar looks fine on the pst file at work, but when I bring the pst home and try to open it on my newly rebuilt workstation it takes the calendar items and stretchs them across a couple of days. Look at the images to see what it is doing ....

I have tried microsoft updates, uninstalling and reinstalling but still the same situation occurs. What has really thrown me for a loop, is that I altered the pst on my newly rebuilt home system and then opened in outlook at work and it looked fine.

Any help would be greatly appreciated, should I move my newly rebuilt system to office 2007? Will it work with my 2003 installation at work?
