Are you asking what:

system clock uses UTC means?

Or how to make the system clock use UTC?

UTC is GMT or Zulu time.  It is the zero time that all other timezones
are + or - from.

Yes. my system clocks are set to UTC/GMT and timezone is set accordingly.

Basically the default of _every_ computing platform outside
of Utah and Washington [state] has been set the RTC to UTC
and offset in software/locale/user-space/etc...

This has really been a key mindset difference between
multiuser platforms and platforms that assume only one user
is on the system, and it would only be used in one timezone.

Especially today with portables -- your hardware RTC should
_never_ change  (except when the UTC time if off), and not as
you merely move timezones.  The OS should _only_ offset,
never modify the RTC (again, except for when the UTC time is
off).
