As mentioned in the post the times reported are the time stamp in the receiver packet minus the system clock time when it was received... negative value indicate the message arrives after the PPS. The polarity of the reported value is consistent with how Lady Heather makes use of the value...

> Are you sure that the arrival time is negative? In my experience, the NMEA message is /after/ the PPS, and not before it.
