Shouldn't it have reached homeostasis? If not, then what is the reference by which time and space were framed upon?

Nico is wrong.
Your statement about Time and Temperature shows insight.
The equation E=Mc^2 includes variables for both energy and Time -> energy can be measured as Temperature (at least Kinetic energy), and the speed of light implies time, since everything that moves takes time.
The reason why everything is not the same temperature is because for our universe, we can point at a start time -> the big bang. which probably did occur.
But more important is the continueing inflation of Space-time.
Plus there is now evidence that the basic constants of our universe have not always been constant. Micheal Murphy of Cambrige University has studied distant quasars, and is saying there is reason to beleive that LIGHT TRAVELLED FASTER IN THE PAST or THAT TIME EVERYWHERE MOVED SLOWER.
The proven effect of TIME DILATATION would be enough to create temperature distributions. particles of different sizes and energies have clocks that perceive time differently.
Also, matter is not simply filling a fixed volume of Space-time, space-time and mass-energy are growing together, and theoretically capable of contracting, together.
Your thinking is still somewhat Newtonian in nature.
you don't understand Quantum mechanics, or the Uncertainty Principle.

When the Big Bang happened, everything was about the size of the head of a pin. Everything here means the whole contents of the universe; energy, matter, everything. Because of this, everything was very very hot, but as the universe expanded, it cooled off. Matter started to condense into the forms we know (atoms), and the four forces (gravity, electromagentism, weak nuclear, and strong nuclear) all seperated out. Basically the universe hasn't been around long enough for everything to reach the same temperature. Enevtually, since the universe is expanding at a faster and faster rate, we will reach what is called "heat death" where everthing in the universe will be the same temperature. I'm pretty sure that won't happen in our life time.

Time isn't forever. It had a beginning, and it will have an end.
At some point (around when He created the Heavens and the Earth (somewhere around 6000 years ago), God created (and started ticking) Time.
Before He created and started Time, Eternity past was all there was.
It will end at some point, and after that Eternity Future will start.
You're dead right, tho', obviously, about how if Time (going back into the past) were eternal and had always been going on, then everything would be the same temperature.
All heat would have dissipated by now, and everything would have found the same temperature.

shollstien is correct - there has not been sufficient time for the universe to come to equilibrium. In the early expansion of the Universe there was an inflation - where space / time expanded briefly at a speed greater than the speed of light. A point as small as a nucleus of a cell would expand to the size of our galaxy.
As a result there are points in the Universe where the light has not yet reached us. This explains in part why the night sky is black. But that would be another question.

The big bang happened some 14 billion years ago and that time is much too short to equal out all temperature differences in the universe. But wait for some more hundreds of billions of years and then the whole universe might be in the same state all over (if we live in an ever expanding universe that is).

you have things like magnetic fields that stir things up. Angular momentum due to gravity also stirs things up. There is also things like atomic decay and atomic fusion that keep occurring. All of these things either directly or indirectly (via friction) causes temperature variances.

wtf does that have to do with temperature? that's like saying:
"If my name is Carl why isn't there peace in this world?"
absolute nonsense
