I don't have one handy, BUT I saw this SAME problem across oh, 20 machines. Every one. Every time. And oh, by the way, when one of them (mine) was upgraded to the newest ntpd, it *WENT AWAY*. Thus, I think its quite reasonable to say its not the clock and must be the code (since the hardware could not have magically changed :-) > Do you have any refclocks we can use to measure against ? Had one at MCS (Spectracom WWV receiver), but its there and I'm here. It appears from their strata change (from 1 to 2; I chime off them) that they turned it off. I should have taken it with me when I left :-) BTW, speaking of which, does anyone know of a reasonably-cheap GPS receiver that (1) has an external-able antenna that will work with somewhere between 50 and 100 feet of lead, and (2) has the appropriate pps outputs and such so it can be used for this? -- -- Karl Denninger (karl@denninger.net) Web: http://childrens-justice.org Isn't it time we started putting KIDS first?
