Mark,
Thanks.. I was hoping to figure out the clock skew between the IMAP
server and the IMAP client retrieving the data. I guess I will have to
come up with something else.
Thanks,
Todd

I want to make sure I am synchronized with the date of the machine
running the IMAP server. I know I can get the date of the message,
but I want the date on the IMAP server. Is this possible?
Short answer: no.
Some servers may announce the date in their banner message as commentary
text, but there is no reason to believe that such a date has any
relationship to the dates in any message. It may have a relationship to
the INTERNALDATE; but note that there are still systems in the world in
which the date is set by an operator's watch at boot time.
In any case, you should not be attempting to synchronize with a server
date. You should synchronize with UTC. Both the message dates and the
INTERNALDATE convey timezone information, which allows translation into
UTC. The quality of that synchronization is based directly upon how
well the client and server clocks are synchronized with UTC. Modern
systems of both types do so, since many forms of authentication depend
upon synchronization.
