Way off topic: Email time stamp issue..HELP!

["John W Rosa" <JohnRosa@xxxx>]

Sorry for the waste of space, but I know several 
of you listers are PC gurus...so please Email me 
directly with any help you can provide.

My PC, a Dell P4 2.8Ghz 256MB-RAM 80GB-HD unit,
has the oddest 'problem' when it comes to properly 
recording/displaying date/time in Emails via MS 
Outlook. My OS is WinXP.

Here's an example.

I receive a note that, in my Inbox list, displays a 
time of 9:00AM. If I hit 'reply', the quoted original 
note's send time is displayed as 9:19AM.
Now, at 6:09PM I send my response, and 6:09PM is 
displayed in the 'Sent' list. But if I hit 'reply' to 
my own note, it quotes the send time of my first 
response as 5:09PM.

Another note I received today LISTS as being sent at 
11:11AM, but if I reply, it's quoted as having been 
sent to me at 11:29AM!

Another lists as 4:49PM, then displays 5:09PM in my 
reply!

Color me REAL confused!!! Anybody got an answer?
Send it direct at jwr@xxxx or the address herein, 
above.
