If you only have Linux on your computer, then it's clock is most likely UTC.

On a Linux computer, the internal clock is almost certainly *NOT* UTC,
rather it is "seconds since Unix Epoch", often shortened to "seconds
since Epoch", or just "Unix time".

The BIOS does not have a concept of time zone. It only knows "seconds since it's epoch". And that's (I think) translated to a struct or string (but not integer, like in Unix) which the kernel reads at boot.

But on the 90% of machines that run Windows, that BIOS time is "local". On "single-boot" Linux and BSD machines (not sure about OSX, though), the BIOS clock is ABSOLUTELY set to GMT/UTC.
