Normally, the official date for a message in the archives is taken
from the "Date:" header which is put on the message by the sending
mail client (MUA) or the first mail server (MTA) to touch the
message. The Internet standards require that the "Date:" header be
present on all messages, but some clients do not create them.
Therefore, most mail servers will automatically add one if it is not
The problem is that many clients have system dates that are seriously
screwed up. They should be running the Network Time Protocol (NTP),
but most of them don't even bother to do any kind of monitoring or
setting of the date information.
Now, recent versions of Mailman have a way to deal with this issue --
see FAQ 3.63. However, this does require a change in the mm_cfg.py
file, which has to be done by the site admin. If you are using a
hosted list service, you may not be able to get support from the site
admin to perform functions like this -- see FAQ 1.32.
