Make sure the clock is set correctly in the BIOS, this will have the biggest impact. The way you set your timezone varies between distributions. Have you tried right-clicking on the clock on your Gnome desktop? That gives you options to set the system clock.

Use the date command to set the date/time for your system.
You need to be root (su -) or have root priviledge (sudo).

sudo date -s "07/04/1776 13:14:34"
Set the date to July(07), 4th (04), 1:14:34pm (1314 :34), 1776 AD

But the real answer is to use ntpd (network time protocol) to update your system time daily. ntpd is the daemon that contacts the time server(s) and synchronizes your system with accurate stable world clocks.

Google is your friend...
Google Search "linux ntpd client"

My problem with ntpd is udp port 123 is firewall blocked in my corporate environment.
If you are on an open network, then update /etc/ntp.conf to add servers and turn on ntpd.
Now your system will update its time.
