How to fix system clock from changing when dual booting between Windows 7 and Zorin OS 6

1.  Boot into Zorin OS 6.

2.  Open a terminal (Ctrl + Alt + T).
     Type the following command:
           sudo gedit /etc/default/rcS

Look for UTC=yes and change this to read UTC=no.

3. Save file and reboot computer.

The system clock should now be the same whether you boot into Windows 7 or Zorin OS 6.
