Why is the clock on my pc always wrong when I switch between OS?

I have PC with dual partition. One has Windows 7 Home and Office x64 and Windows 8 Pro x64. Whenever I start an OS the time is always wrong. For example, if I use Win 7 today until 7:00. Then I restart and open with Win 8. And then I shut down at 10:00. The next day when I open Win 7 at like 3:00, the time says 7:00. So essentially my time will be the time I shut down the last time I used the OS. I have this problem with both OS's.
