Keven, The TrueTime driver that lives here supports all known TrueTime receivers, including GPS, WWVB and GOES. I strongly suspect one or another of those receivers would not work if the poll interval was tinkered. EndRun apparently has cloned most or all that driver and may have modified it. If they recommend minpoll 4, run that end.
