Time and space are static and infinite. Any ongoing events such as the universe expanding or shrinking give the illusion of elapsing time. When the universe big crunches down to a state of zero dimension there will be no events happening to give any illusion of time.
When someone asks you 'what is the time?' just show them your watch which has the hands removed and tell them that the hands of a watch moving around the face just give the illusion of time and time does not exist.

Time is the measure we use to determine the period between events. The methods and measures we use remain constant, irrelative to the proportions of space. This known as Ultimate Time.
There is a theory in physics, one that I don’t fully understand, called Thread Particle Network Time, that in the course of our limited existence may not make much of a perceivable difference from Ultimate Time.

I knew you'd weigh in on this one. I learned a lot of new terms in your answer. But are you saying there is ONLY ONE theory in physics you don't understand? Of course not, but that reminds me of a scene from Batman, the TV series:
Robin: "Golly, Batman, is there anything you don't know?" Batman (looking down, deep in thought, perhaps a little troubled): "Yes, Robin, in fact, several things."
Time does not expand, in the way you are referring to space as expanding. If it did, a second now would be equal to only a fraction of a second at a future point in time.
IE: There would still be 60 seconds in a minute ... but the actual pause between ticks of the second hand would increase.
If the rate that time passes is changing for everything, including your brain activity, at the same rate would you even notice the pause between ticks?
Hmmmmm ... I'd guess probably not. Which would tend to prove time is not expanding, would it not?
Example: We can bounce lasers off the surface of the Moon, and prove that is it moving away from the Earth based on the time it takes those results to come back. But if time is expanding, then those results would take the same time no matter how far gap between the Earth and Moon.
