Why does my computer have the wrong time?

Computer time is wrong?

• Every time I reboot the computer, my computer clock is exactly five hours ahead of what it should be. I'm running a PC with Windows and Linux installed and it happens in both operating systems. Furthermore, the computer is brand new (less than a month old) so I don't think it's the CMOS battery. The interesting thing is that I'm in the Eastern timezone and every time I reboot it shows the time 5 hours ahead, which would be GMT (I wonder if there's a connection). Anyway, how do I fix this?

• Answer:

  Windows uses localtime for it's time settings, while Linux uses UTC; these two different methods are conflicting with each other. It's a very common dual-booting problem. Here's how to fix it: 1. In a Terminal, run "sudo gedit /etc/default/rcS" (no quotes). 2. Look for the line that says "UTC=yes" and change it to say "UTC=no". Save and exit. And that's it. Ubuntu has now been set to localtime, and won't conflict with Windows any longer.
