KC2MMI,

Thanks, but we aren't talking about PC's we are talking
about digis, and 99.9% of them do not have good clocks.

Bob-
 Under Win9x and NT4, NT5, accurate timekeeping was optional. Under XP
and
later versions of NT, timekeeping is no longer optional it is a
mandatory
part of security and networking communications. If the system clock
error
exceeds something like 15 seconds, authentication routines fail and 
you'll
see 'invalid certificate" errors on the internet. XP and later versions
of
NT are designed to synchronize with internet time services
automatically,
transparently to the user.

 So no, sysops may not be syncing their clocks. And no, they may not
be
using current OSes. But accurate time on PC's has become the
standard--at
least on all new PC's that are networked to a server or
internet-connected.
As WiFi continues to deploy (and there are high-power large range
versions
coming SOON) it will become ever more common to see near-GPS quality
time
accuracy on PCs. As the norm.

 Might as well anticipate that and make use of it. (And that's ignoring
any
digi's which are using GPS-time to set their system clocks.)
