PS - When I was in the BIOS I did not see an option to select or change time zone data - I saw date/time and that's it.
That's because the computer clock only knows whatever time you set it to. It has no other means of being set, so no need for time zones. In this respect, it's no different than any alarm or stove clock. On the other hand, NTP servers, which can be anywhere in the world, provide UTC, which a computer then offsets to local time. This is where the time zone comes in.
