Just to clear up any confusion regarding your question:
The date command has a --utc option. Without it, date will
display (or with --set, will set) the system clock in your local
timezone. But the system clock is still always in UTC; it's
just transparently converting it to (or from, if setting) your
timezone unless you specify the --utc option, in which case no
conversion will take place.
