System Date and Time
Yes date&time must be setup correctly, otherwise your cron job will blow your head off.
Before you change the date you must pay attention to your timezone.
Simply execute # timeconfig from the shell.
Timeconfig not working ? It must be installed first.
# yum install timeconfig
Here is some common use to set the date and time of your box
#date –set=”1 JUN 2009 12:28:00″
That will change your Date and time with the correct format and time zone.
