No.
Every minute, 60 seconds went by (or is it the other way around?)
Mass density does not affect time rates. For one thing, time rates are always relative. You OBSERVE things happening slower (or faster) somewhere else than where you are.
For another, it takes heavy gravity fields to change the observed time rates.
The observations astronomers make, of distant galaxies, show that things happen inside them at the same rate as they do in our solar system. There is something called "red-shift", caused by the fact that the far galaxies are speeding away from us. But this is easily corrected for. For example, if a certain type of star takes 1 hour to explode, and we see it take 2 hours in a distant galaxy, we don't say that it really took 2 hours. We say that it took 1 hour, but the light from the explosion was stretched out to 2 hours because the star is moving so fast away from us.

the present radius of the universe is calculated to be = 3 × 10^26 meters. From V = 4/3 pi R^3 the volume must be = a million.13 x 10^one hundred ten m^3 The density of the universe is calculated to be = 2.11 × 10^-29 kg/m^3 (about one hydrogen atom in 50 cubic meters of area) Now we may be able to calculate the mass of the universe... M = D x V = (a million.13 x 10^one hundred ten m^3) x (2.11 x 10^-29 kg/m^3) = 2.329 x 10^80 one kg (heaver than your undemanding undergo)

In the earliest state the universe wasn't much more than dust scattering from a massive explosion. Therefore I would think that at that time the mass would be so evenly distributed that it didn't really have much effect on time at all. :-)=

Time is but one of humankind's inventions, albeit a very useful one. Therefore, time was running neither slow nor fast.

that is one of many theories. if your really interested in the topic read the theory of everything. its one of my favorite books and hawking has a way of putting things in very simple terms.

Well, yes. When I was young, there was a heckuva lot of such density; you see, my parents were Republicans....
