You like to live dangerously.  :-)

Personally I just use NTP and configure proper time zones.  It's been
many years since I encountered either of the situations that you
mentioned.  Perhaps I lead a sheltered life.

Come to think of it, I do recall running into clock skew issues with
"make" with NFS and parallel builds in a cluster, where the time
stamps were only small fractions of a second off.  For this sort of
application I suppose a "human_time" module should report something
like "35 microseconds", which I suppose is mildly more useful than
"3.5e-05 seconds".
