Its a bullshit argument David and is nothing other than BLATENT shilling for Motorola - at someone else's expense! Without a specialized board that counts these nanosecond ticks from the time it gets the PPS signal to the time the latch is read this kind of accuracy claim is worth exactly NOTHING. WITHOUT it, which is EXACTLY what REAL WORLD use of these devices is going to be running under, the impact is ZERO. Further, the ACTUAL impact in the real world of time stability to the dozen-nanosecond-range is ALSO zero, with the possible exception of physical control processes in the nuclear research field (such applications are NOT running on "standard" Unix machines!) Finally, in the world of sync'ing time between systems (say, in a multiple server cluster) that kind of precision is ALSO worth ZERO! NOBODY with off-the-shelf hardware can obtain repeatable 10ns results from a standard Unix machine. NOBODY. And THAT is a fact, easily determined through nothing more than Intel's databooks on their processors and the interrupt response time they exhibit. -- -- Karl Denninger (karl@denninger.net) Web: http://childrens-justice.org Isn't it time we started putting KIDS first?
