Because hardware clocks are seldom accurate?

Linux has its own system clock which is run off timer interrupts. This

Good to know.

For today's humor:

"Some Linux distributions attempt to automatically calculate the System
Clock drift with adjtimex's compare operation. Trying to correct one
drifting clock by using another drifting clock as a reference is akin to a
dog trying to catch its own tail. Success may happen eventually, but great
effort and frustration will likely precede it. This automation may yield
an improvement over no configuration, but expecting optimum results would
be in error. A better choice for manual configuration would be adjtimex's
--log options.

It may be more effective to simply track the System Clock drift with sntp,
or date -Ins and a precision timepiece, and then calculate the correction
manually."
