In Mac OS X.2 (aka Jaguar) using built in Mail, does anyone know how
to change the time stamp that Mail puts on outgoing messages?

I tried changing the system clock in System Preferences->Date and Time
and it doesn't seem to effect Mail's time stamp...

Does anyone know how this can be changed (so if I'm sending an outgoing
message it wil have a different time than the 'real' time)


thanks in advance
