I am running a Garmin 18x LVC with PPS enabled; it is very stable and I 
beleave it to be accurate.  My nearest back-up server is consistantly 
around -8.625ms away.  This is so much that other clients on my network see 
me as a false ticker even with a prefer setting.  I am on a farly fast ADSL 
connection to the internet, but of course, it is non-symetrical.  Other 
users I have conversed with don't seem to have this wide of an offset, so 
something is wrong somewhere.  Yes, I can fudge the offset away on the ref 
clock, but it doesn't seem right to tell a ref clock to lie about what time 
it is just to keep
everyone else happy?
