Thanks Garl...

This looks very very similar to what I tried the other day and I got my 
machine's time all fubar... the 'w' command would show a time 8 hour sin 
the future, system clock showed current time... messing around with them 
just made it worse... luckily I had backed up /etc/locatime and could 
recover..

Followed the above verbatim and have the same problem.... the only thing 
w/ correct lines are /America/Los_Angeles

Again, glad I had a backup....
