This line of discussion causes, to me, funny quirks of logic.

"If you take reality to be right here, right now (what else could it be?)" - can't disagree!

But, after that, things start to get self-referential in tangled ways - "time cannot exist, it just helps us map change" - but 'change' requires time! And 'mapping' is a mental act that involves change!

I can't help but feel that if these apparent contradictions were ironed out, the answer to 'what is time?' would be close by.
