I've been wondering when someone would mention this, and I kept not doing it
myself to avoid 37 similar messages as everyone sent the same message...  Oh

But how about a simple Perl script to do the same?  Heck, you could probably
do it with awk pretty easily too.  Both of those run on Windows or UNIX, so...
Here is a one line Perl (command line) program for UNIX (one-liners on Windows
are hard because of quoting issues):
cat mylog | perl -npe 's/^(\w+\s+\d{1,2} \d{2}:\d{2}:\d{2})/$1 EST /'

Try tailing /var/log/messages into the above Perl to see what it looks like,
then use the "real" log and redirect the output to a new log file name and
you're set.  If you need help to write the Perl code send me a note offline
and I'll give you a hand.  I can also post other code to the list if anyone
else cares.

To CONVERT a time stamp is not trivial, but to just add TZ code is.  Did they
say what format (e.g. EST, EST5EDT, or UTC-0500)?
