calculating system clock resolution

[MrJean1]

Depends .... iff you are using Linux, print

  cat  /proc/cpuinfo

and look for the line "cpu ...Hz: ...".  Parsing that would be
straightforward.

Keep in mind, the time.time() function reports the "wall clock" time,
which usually has up to a millisecond resolution, regardless of the CPU
speed.

There is also time.clock(), more about that on
<http://docs.python.org/lib/module-time.html>
