Yes. Its primary timescale, sometimes called "PTP Time", more properly the "PTP

seconds). Note its origin, or epoch, is 1969-12-31T23:59:50Z, ten seconds before
the POSIX "the Epoch" (if you take that to mean two years (2 x 365 x 86400)
seconds before 1972-01-01T00:00:00Z (UTC), as NTP does).
Just nitpicking:
In [IEC 61588 of 2009-02. section 7.2.2] we read:
"The PTP epoch is 1 January 1970 00:00:00 TAI,
which is 31 December 1969 23:59:51.999918 UTC."
So you are off by about 2 s.
