Hi everyone,
Some time ago there was a discussion about what effect the asymmetric
latency on DSL lines has on the ntp accuracy.
The generous people at Meinberg (http://www.meinberg.de/english/) sent
me one of their time servers
(http://www.meinberg.de/english/products/lantime.htm) to use
for/in/with the pool.
I've had it at home to help test some of the new monitoring code I'm
working on and I can confirm what others have said: The "A" in ADSL
has minimal or no impact. I've put the current "peers" output below.
As far as any stable path asymmetry between a pool server and its ISP, there
is a feature which may be of some interest. This asymmetry shouldn't bother
any timekeeper without own refclock. Its server has an offset but a client
doesn't see it. Sorry if too self-evident.
