So does Linux. But the interrupt processing ( and eventhe clock reading times) are nowhere near that accurate. The interrupt processing is on the order of 1-2us accuracy, with possible delays of up to 10us occasionally (because other interrupts do not allow themselved to be interrupted for example). > LVC PPS signal has only microsecond accuracy, then I suppose there is > no point on using FreeBSD, any linux would be okay as well.
