Why aren't computer clocks as accurate as cheap quartz watches?

OK, thanks, but why is it so important?
Sometimes you have to be able to correlate or synchronize events over
long distances with great accuracy (fractions of a second).
A message is received on one computer at a certain time per that
computer's clock. It was sent from another computer at some time,
recorded in the message, per that computer's clock. Are we going
to calculate transit time or something?
Yes.
Check to make sure it didn't arrive before it was sent?
Yes.
There are many applications for accurate time. In fact, the more
accurate time one can obtain, the more useful applications become
practical and available.
