One is the assert edge of the PPS, the other is the clear edge.

So, the assert happened at 1468700910.979003708
And the clear happend at   1468700911.078993120

So about a 200 milliSecond pulse.

You gotta change your ntpconfig to use dirver 28, not driver 20, with gpsd.

Only one of ntpd and gpsd should use the serial port at the same time.
