You could try powering down system, disconnect from the wall and remove CMOS battery from the board. Replace after 30 minutes and then see if the clocks go to defaults.

Which version of Windows 10 are you working with? Make and model of your motherboard? You might want to also see if you've got any BIOS updates pending on that motherboard of yours.
