|telnet to port 13 is what i'd do as a first pass...

i sent mail to the original requestor suggesting that they use the smtp port
since most (many, all?) bsd sendmail announce the date *and* local timezone.
many (most, all?) daytime ports just return the time.  while you can then
determine timezone (which is what we're after here) i thought the simpler
approach was better.  granted using daytime makes shell script construction
a bit easier.
