don't know where you got that from, but ever since the IBM AT, PC's have
had a hardware clock on the mainboard, independent of the OS or user
programs.
The only thing that can make those thing fail is an empty battery or
broken crystal.

The crystals that make these hardware clocks tick aren't the best in
terms of stability or accuracy of course, but with ntp for a daily
dosage of 'realtime', there's nothing wrong with the basic concept.
