The standardized messages exactly implement the 1588 standard, so
please refer to that document.

The custom message fields aren't documented, so you'll have to look at
the source code.  FWIW, you asked about TIME_STATUS_NP:

  master_offset              0    nanoseconds
  ingress_time               0    nanoseconds

  # For the next four, see "Follow_Up information TLV" from 802.1-AS

  cumulativeScaledRateOffset +0.000000000
  scaledLastGmPhaseChange    0
  gmTimeBaseIndicator        0
  lastGmPhaseChange          0x0000'0000000000000000.0000

  gmPresent                  false  Boolean
  gmIdentity                 e89a8f.fffe.74f796  ClockIdentity

HTH,
