The support people, you mean.  Although there are days I think the 
same about the true techs.

After some other comments I decided to go NTP hunting - traceroute 
to some site, then ntptrace each host in turn.  The neighborhood 
switch has NTP (but the upstream stratum is non-responsive)... and 
no other blather.att.net site is running NTP.  (Or responding to 
the likes of me.)  Meanwhile the first non-AT&T site does respond 
with a Stratum 4 time server that traces back to a GPS, and about 
2/3 of the remaining sites trace their time back to various 
sources (e.g., I saw a USNO in there).
