You have users who read Recieved: headers regularly? Why? At any rate, it
really ticks me off when SMTP servers use local timezone values in
Recieved: headers -- try tracing a message that got to you from Finland
across a good five or six servers that _all_ use local timezones, doing
the GMT math by hand, to see how long the message took to get to you. No
fscking fun at _all_. Using GMT in Recieved: headers means that it's
_very_ easy to find out exactly how long it took to get to you, and
where any delays might have been (and what else is the date in the
Recieved: header for?). Doing the simple math to convert it all to your
local timezone should be trivial, you only need to do it once.

I imagine that it's trickier than you think if you're avoiding standard
C libraries, and most sysadmins (which is who I thought Recieved:
headers were for) seem to prefer GMT anyway....
Is your problem actually with the Recieved: headers, or 'Date:'?
