Hi Richard,

There aren't thousands of pages, but it is steeped in
legalese.  Bottom line is that the US DOJ is petitioning
the FCC for a mandate to institute a time-stamp "accuracy"
of 200 milliseconds for all network operators and
voice (including VoIP) providers - likely substantially
relying on NTP.  Almost all other countries have similar
requirements on the order of one second, which
will likely be reviewed through global standards bodies.

>Was there some point you were trying to make?

The following questions seem applicable:

1) Are there timestamp implementations/specifications
that capture "NTP-friendly" values like offset and jitter?

2) Are there recent surveys that indicate the extent of
NTP deployment across network infrastructures?

3) Are there any recent surveys/crawls that indicate
the state of clock accuracies across infrastructures?
Back in the 80s and 90s, there appear to have been
several done.  Is there anything recent?

thanks in advance,
tony
