37 seconds is the offset between TAI and UTC due to leap seconds.
You are distributing TAI via PTP, and somewhere putting the TAI value
directly into the system clock rather than accounting for the offset to
UTC. The ptp conf file has a field for UTC offset or you can pass it in on
the command line.
