Does a remap leave a time/date stamp?

[Chromag]

Need to find if it is possible to trace a time/date stamp on a car that has been remapped. Bought a car which is not as it seems and a potential warranty claim could be a necessity. Dont want to give away too much just now but definitely in need of some help please

sorry mods just realised i probably have this in the wrong forum. Will repost in the tuning section.

Nope, no date/time. Only a flash counter.

And the dealership will pick it up at service/code reading.
