Working perfectly here with GR601-W and the EVK 6H. Screenshot of the

Based on Hal's advice, I killed gpsd, and asked gpsmon to look at /dev/ttyS0.
I can see a value for PPS Offset, as will as the -----PPS---- lines.
This is with gpsmon pointed directly at the device (gpsmon
/dev/ttyUSB0), not indirecting through the daemon. When going through
the daemon you won't get PPS packets in gpsmon; superraw mode doesn't
pass them through. I should add that caveat to the manual page.
Please, please, do. I think I wasted your Friday evening due to this.
I think the smoking gun is the absence of "PPS edge" messages in Sanjeev's
gpsd log messages. Edge detection is failing for him; Gary, is it for you?
gpsd MUST be seeing some edge, as it passes it on the ntpd.
gpsd should pass this to gpsmon as well (in an ideal world)
If that is not possible, then we need a clear waiver in the gpsmon documentation, and gpsmon should show "Not Available" in the "PPS Offset:", not leave that blank
