Cosmological time scale

How long is a cosmic minute?
And with the passing of every cosmic minute — each minute 30,000 years long — we began the arduous journey towards understanding where we live and who we are..
What is meant by cosmic time?
Measure for the progress of the evolution of an expanding universe such as that of the big bang models.
It corresponds to time as measured by clocks that are at rest relative to the expanding space, and that have been set to zero at the very beginning, the time of the hypothetical big bang singularity..

The time scale of the universe refers to the relative size of the universe and all events occurring within it.
Best estimates show that the universe has been around for 13.8 billion years.

The Cosmic Calendar is a scale in which the 13.7 billion year lifetime of the universe is mapped onto a single year. This image helps to put cosmology, evolution, and written history in context. At this scale the Big Bang took place on January 1 at midnight, and the current time is mapped to December 31 at midnight.

The Cosmic Calendar is a method to visualize the chronology of the universe, scaling its currently understood age of 13.8 billion years to a single year in order to help intuit it for pedagogical purposes in science education or popular science.

Should the clocks measuring cosmic time move along the Hubble flow?

The clocks measuring cosmic time should move along the Hubble flow .
Cosmic time is a measure of time by a physical clock with zero peculiar velocity in the absence of matter over-/under-densities (to prevent time dilation due to relativistic effects or confusions caused by expansion of the universe).
