I opened an Excel sheet on my BB with some dates in it.

I noticed the dates were all off by one day. For example, cell c15 in the sheet displays 27-Sep (behind the scenes, it states 9/27/04) but on the BB it shows 26-sep.

I checked my dates on both the PC and the Blackberry, and I'm feeling rather foolish, because I can't find anything wrong. I'm thinking I might need to reinstall the attachment service pack or something.

Any ideas? BB 7510, os 3.7.2 from Nextel.

This is just a hunch, but you might want to check and see that both devices are set to the same time zone, and that your time and date match on the PC and the Blackberry...keep us updated...this is an interesting one...

Well, I just checked, and the time zones are both Central.

Dates are the same too. I'm starting to think that the attachment as coming from the BES server is wrong.
