Yep. Try `man hwclock' on your own system. Should be the same thing.
That's the first or second document one shd. read to learn about
system clocks. (The other is the `adjtimex' man page.)
Then, if you want to go deeper, start reading David Mills' documents
on the NTP time protocol. It really is a wonderfully complex and
fascinating technology. People who have experience with PLLs (phase
locked loops) and feedback systems will delight in it.
