In message <[EMAIL PROTECTED]> Alexander Leidinger writes: : systems which have a more or less precise clock attached (e.g. GPS or : atomic clocks which sync the system clock via nptd)? And what are the : numbers for this solution (for those people which are interested in : numbers to be their own judge)? I can tell you right now that the variation between GPS and a good cesium clock is on the order of +- 25ns. With nanosecond resolution, this gives you about 5 bits. The variation of the system clock when synchronized to the GPS receiver is on the order of +-10us as measured with a parallel port interrupt and a pps line from the gps receiver. The pps interrupt is measured using a fast interrupt (we hacked ppc to do fast interrupts for this), so the latency is fairly small and fairly constant. I don't have datasets that I can point people at, however. Warner To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
