what is "perfectly accurate?"  perfection is not very realistic.  to
what use do you put these logs?  what precision and jitter are required
for that use?

imiho, if you are just comparing router and server log files, run off
public.  if you are trying to do fine-grained measurement, you are going
to invest a lot in clock and propagation research.

i would generally let customers chime off routers which are strat 2 or
3.  if a customer has other needs, then they can deal.  if they are
really concerned, they should not bet on me anyway.

again, depends on your needs.
