Upon upgrading from 22.04.4 LTS to 24.04.1 LTS ntp went insane. ntpq -p shows: xNMEA(0) .PPS. 0 l 12 16 377 0.0000 -96.8229 0.5427 Previously that 'x', which means the source is being rejected, was 'o', which means the source has pps, and the offset, which now shows as -96 milliseconds was under 1 millisecond. From syslog: ntpd[10299]: REFCLOCK: refclock_params: kernel PLL (hardpps, RFC 1589) not implemented ntpd[10299]: REFCLOCK: NMEA(0) set PPSAPI params fails It appears that the ppsapi has not been implemented in 24.04.1 LTS which makes it useless as a stratum 1 ntp server.
