You can do even better. Connect the pulse to pin one (DTR?) This is the same pin used for the PPS from a GPS unit. The Linux (or BSD) ...
Chris, Then the next step is to use an NTP driver that treats the 60 Hz pulses on DTR as the local time/frequency reference. Your PC will then run on "mains time" instead of UTC. Not sure how low a stratum that would be. Still, if you did this, then your existing NTP tools will give you all the logging and plots you need. Your PC is running mains; the rest of the network is UTC, so any time drift plots for your server will neatly indicate if TEC is working, or not. /tvb _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
