I think that with "the end of time" is meant: The end of the illusion called "time"
That means that there will exist no more time for the ones that see through the illusion we now call time.
That of course will have immence consequences for this 3D world if the number of people becomes bigger and bigger reaching a critical point that, as we all know will start influencing and changing everything around it.
Remember how Jazz changed the world and cars and flower-power.
The ones seeing through the illusion will live in the NOW.
The ones living in the now will see all timelines and will be able to live them if they so choose.
I can think of a horrible scenario that you will be forced to live them all but I can't see anything to cause that (although that could be exactly what happens in the moment of your death).
Speaking of timelines and Hillary Clinton:
Who do you think the guy in the background is?
