Can someone help me understand the time signatures on emails? Every

Where does this time signature come from?
Is it the time it is sent? Time received? Time through the net?
Thanks
In the email I am looking at, the time in the MS Outlook Express
"Received" column seems to match the time in the topmost "Received:
from * by *" header line.
Compared two messages:
MSOE matched the header:
Received: from smtp112.sbc.mail.mud.yahoo.com ([68.142.198.211]) by
bay0-mc7-f16.bay0.hotmail.com with Microsoft SMTPSVC(6.0.3790.211);
Sun, 12 Mar 2006 12:25:03 -0800
MSOE displays one hour earlier than the header:
Received: from 131.107.70.12 (EHLO
ext-imc-04.partners.extranet.microsoft.com) (131.107.70.12) by
mta155.mail.mud.yahoo.com with SMTP; Tue, 09 Aug 2005 20:45:10 -0700
For the last one, there is one other anomaly: The header is the
topmost Received header line of the original message; but it was
forwarded, and the topmost Received header is not the one whose time
is displayed by MSOE:
Return-path:
Received: from mta155.mail.mud.yahoo.com (68.142.202.87) by

MSOE displays "8/9/2005 19:45" for this one. Also, when MSOE is off
by one hour, adding the current UTC offset to the displayed time
produces the same sum as adding the header line UTC offset to the
header line time. I.e.:
Header line time plus header line UTC offset:
20:45:10 + 0700 = 27:45:10 (or, "8/10/05 3:45:10")
Current MSOE displayed time + current UTC offset:
19:45 + 0800 = 27:45 (or,"8/10/05 3:45")
I did some more digging. OE seems to be displaying the time my POP3 server
received the message in whatever Received line has my server at the end.
Adjusted for time zone differences.
