First of all, sorry for not replying to this thread sooner. Xmas and all ... 1. Can you restart you machine and set the right time in BIOS/EFI?
I had already done that, as mentioned in the original post. 2. Do you have other OSes installed on your hard drive - windows for example?
Nope. Just Sparky. Will probably be installing CentOS on a partition I set aside for that in the near(ish) future.
Time and date are now correct, but I can't explain why/how. I have a vague recollection of trying to fix the time after having drank more than my share of fine Xmas spirits.
I have no idea, though, what I actually did. The next time I looked on the BIOS time settings they were way off. I set it to the correct UTC time which I'm sure I had checked before I started this thread, and after setting it correctly Sparky OS now has the correct local time.
My guess is that the BIOS time was wrong from the start and I just misread it when I first checked. Thanks for your assistance and I'm sorry I wasted your time.
