email timestamped from the future..

[jmcws]

System:
XP Pro, Outlook 2003

Situation:
I'm receiving some, not all, emails that are timed stamped 5-30 minutes
ahead of the actual time. My system clock is set correct, the sender's
system is the same time. This has only recently happened. There are
situations I have, that the accuraracy of arrival time of emails is very
important.

Possible Variable:
I have a blackberry 8130 that recieves the emails as well. The phone/network
time is the same time as my PC.

Question:
Why is this happening and how can it be corrected?

Thank you,

Jason
