I have a u-blox M8T connected to an i210-T1 and am trying this config with ts2phc 4.0
[global] ts2phc.pulsewidth 100000000 ts2phc.tod_source nmea ts2phc.nmea_serialport /dev/ttyUSB0 ts2phc.nmea_baudrate 9600 leapfile /usr/share/zoneinfo/leap-seconds.list [enp1s0] ts2phc.extts_polarity both I have chrony controlling the system clock using a GPS-connected local NTP server and after the offsets have settled down I compare the PHC and system clock using: phc_ctl enp1s0 cmp I get results that are close to 36.9 seconds (e.g. -36899918303ns). If I remove the tod_source line (so it is using the generic source), I get results that are close to 37s (e.g. -36999949290ns), which is what I would expect.
