I ran ntp at our community TV station using a USGlobalSat EM-406
module with no working PPS (it has the pin, but I could never get
pulses out of it.)   NTPd (the Meinberg distribution) ran fine on this
module once I got the offset figured out.  I don't recall what figures
I got since I replaced the module with a Garmin GPS-18x LVC with a
working PPS but 50 mS sounds about right.
