Time is defined by events. Once the heat-death of the universe occurs, there will be no time, as there will be no events.

Sir Roger Penrose has a theory that the heat-death of one universe is indistinguishable from the singularity from which a new one emerges. Both are instances of the highest possible entropy where time, space and mass cease to have physical meaning. https://www.youtube.com/watch?v=z2_6h15UCMg

How is time defined? By events. Or is there another way to figure out how much time has passed.
