Computers have keep time 'well enough', with the .001 percent crystals.
I doubt that you would be satisfied if the time-drift is so bad that
'make' no longer works.
I also am quite aware that machines may be "more-or-less" synchronized
to NIST. I do that with my time-server. The problem is that there is
a concerted attempt to minimize computing machinery so that they will
only work when connected on-line, perhaps to a Micro$oft-mother.
We have to make certain that Operating Systems remain divorced from
such new "technologies".
