Sorry I wasn't clear.

I'm looking for the same info that goes into the non-PPS SHM slot - the 
offset between the time the packet arrived and the time in the packet.

If I give you a screen shot of gpsmon watching a unit without PPS, can you 
tell me how far off the system clock was?

These are my opinions.  I hate spam.
