The clock time on TERB is TERBs server,, Fred is looking into it

set the time sync to use tock.utoronto.ca or tick.utoronto.ca
 
It has nothing to do with your computer, the server time is wrong

terb should log into their server (I like using putty.exe) and issue the following command :

date -s "05/19/2005 23:55:00"

if they use a unix server
