How can blackholes warp time? What is time?

Im kinda piggybacking from an older post, where the OP asked what exactly time is. How can the blackholes warp time, if time (as i know) only a measurement on how old everything is?

*Age* is a measurement of how old something is.

Time is a measurement of the rate of change.
An object’s “time” is also described relative to another thing’s “time”.

Time and space are (as far as we know) bound together and inseparable. If an object is massive enough to distort space it will also distort time.

A black hole is a really massive object compared to the earth, so space (and this time) become stretched, and elongated. Time around it moves slower *relative* to the time on earth.
