  As long as the end-user is made aware that the accuracy of said NTP clock
  is +/- 30.000 seconds (or whatever jitter might exist).  Seems kind of
  ridiculous to use an NTP source that is, for many purposes, wildly
  inaccurate.  For my purposes, wildly is more than +/- 0.1 seconds.  Trying
  to troubleshoot a problem, network or server, where the timestamps on each
  server/router/device vary inconsistently, is like walking on broken
  fluorescent bulbs -- painful and dangerous to one's health.
