I first recall him trying to shoulder surf Linux’s popularity not long after the XFree86 project switched to a new license that included an acknowledgement clause, so around 2004/2005. I still chuckle when I see that he wants me to call it GNU/Linux, but he has a shit hemorrhage because XFree86 added a license clause requiring similar labeling. He’s made more than his share of contributions, but he takes pedantry to a whole new level.
When you power the system down, unplug it from the wall for ~10 minutes, plug it back in, then power it back up, is the BIOS clock off by an hour again? If so, I’d follow the recommendation to replace the CMOS battery. If you look your motherboard up online, you should be able to find the location on the board and type of battery. It isn’t a complicated task, but it can seem difficult if you’ve never done it before.
