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!
