I dual boot my computer between Ubuntu and Windows 7. After my upgrade from Ubuntu 12.04 LTS to 14.04 LTS, I noticed that my clock was wrong in Windows. It was obvious that my hardware clock had been on EST and got switched to UTC during the upgrade. The worst part, I think, is that I even remember getting asked during the upgrade what time zone to set the hardware clock to. I guess the default changed, since my result was different.
I knew there had to be a way to fix it, and a quick search showed me the answer. Ubuntu hardware clock correction
My preference is to make Windows use UTC:
