Coordinate time is clock time, proper time is P-time, at least as I interpret it. Notethe important, crucial, point that clocks measure only clock time.

?? Clock is proper-time along the worldline of the clock.

P-time can't be measured by clocks but it is measurable by Omega, the curvature of theuniverse (see below).

`So you're taking the FRW spherical, homogeneous cosmology as "the clock" that measures`

`P-time. And then coordinates in which the cosmic microwave background is isotropic are`

`privileged.`

However P-time is experienced, and in fact our consciousness of the present moment isthe basic experience of our existence.

`But we, the Earth, is not this privileged frame. There is a dipole temperature gradient`

`in the observed CMB due to motion of the Earth.`
