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.
