I'm finding my clock time in Windows 7 jumping hours. I just reset it, and even in the time it took to come here and mention it, it went from 12 to 1 to 2 to 3, and yes, just this moment jumped to 4am. What's the issue here? How do I stop my Windows 7 clock from adding hours to the day every few minutes? (I'm waiting for it to go from 4 to 5... yep. Just did it!) Help, please!
