Yes.

It syncs the hardware clock with the system clock. The hwclock man page says:

       hwclock is an administration tool for the time clocks.  It can: display
       the Hardware Clock time; set the Hardware Clock to  a  specified  time;
       set the Hardware Clock from the System Clock; set the System Clock from
       the Hardware Clock; compensate for Hardware Clock  drift;  correct  the
       System  Clock  timescale; set the kernel's timezone, NTP timescale, and
       epoch (Alpha only); and predict future Hardware Clock values  based  on
       its drift rate.

It's worth reading the entire man page -- it is extensive,
and gives a clear understanding of just how complicated time management
is -- even without interfacing with ntp!
