This has nothing to do with the iffy-ness of system clocks.  My
disagreemnet is predicated on the stupidity of using a 10 line
example subroutine without actually inspecting what it does on 
whatever OS that one chooses to use.  Perhaps, my expectations
for the IQ of scientists is too high.  Are you suggesting that
every code snippet in the manual should contain a cautionary
comment of the form:

! 
! This is only an example.  Use with extreme caution.
