Not an internal clock exactly, rather a timezone value that is copied 
from the system timezone at launch and not rechecked. A problem easily 
worked around by restarting MailMate, but certainly a bug. Technically, 
it *may* be as simple as changing one system call at launch time from 
defaultTimeZone() to localTimeZone().
