Setting Hardware clock to not use UTC in Ubuntu

I installed Ubuntu on my Desktop but during the install I selected the option “Hardware clock set to UTC”, This messed up the time on the computer as the hardware clock was in fact set to EST. to fix this I had to

1. edit the /etc/default/rcS file with the command

   sudo gedit /etc/default/rcS

2. Change UTC=yes to UTC=no and restart computer
