Glad you resolved the leading/trailing edge issue, Jack. Now we need a way to tune out those remaining few microseconds accurately! It sounds as if your application - like some of mine - would benefit if NTP were able to provide a new function where you could call it on your local PC to get the time, rather than having to use a call via a network packet, with all those overheads. The function would be really simple, taking no arguments: ntpGetTime and returning a 64-bit timestamp value (as per http://www.ietf.org/rfc/rfc2030.txt). Would some kind soul like Dave Hart care to provide a small DLL which could do this - perhaps even as part of his serial kernel-mode PPS support DLL? Perhaps there is some fundamental point I'm missing which makes this difficult, though?
