If you use the NMEA, then why do you think the time service matters? > also with ntp running it looks the same and not converging at all.

It is because of this: /dev/ptp0 ignoring invalid master time stamp I think the message is crystal clear. It says that the SW is ignoring the time stamp. How should the servo converge if the time stamp are being ignored? > Why is the mater timestamp Invalid even when the GPS Receiver has acquired > a fix? The NMEA parsing code is in nmea.c You can instrument nmea_scan_rmc() to see which test fails. (Not every failing test prints a message.) I guess your sentences lack the checksum on the end?
