To change the system date/time in Linux create a symlink to /etc/localtime for the correct time zone.
Verify the new time with “date” then update the hardware clock with “hwclock”
$ ln -sf /usr/share/zoneinfo/America/Denver /etc/localtime $ date $ hwclock --systohc
You can also use ntpdate for NTP (Network Time Protocol)
$ ntpdate pool.ntp.org
$ hwclock --systohcYou will need to restart httpd to see this change reflected in your webserver.
