On a related note, I noticed that my time sources have drifted 
apart by a matter of seconds.  Granted, the worst offender is 
AT&T/Comcast, and I don't recall whether they ever officially 
announced the availability of a NTP signal for customers, but 
still....  (I suspect this might be a victim of the merger - the 
stratum 1 server seems to have become nonresponsive so this server 
is free-running.)

But at the same time, I noticed a significant difference between 
tummy and my colo ISP's time.  Since tummy connects to NIST I tend 
to give it a bit more weight, but the fact that there's any 
difference at all drives home the point that getting an accurate 
time is a lot more than just firing up the NTP daemon.
