Change the date modified on files using a time stamp that is already part of the filename.
This file will also add +5minutes to file modified so creation and modified date are different.
Why is this important?
If you are changing a file that was growing over a period of time which you roughly know, you might want to change its final modified time stamp so its not the same as creation date.
An example is a large .log file you want to change back its modified/creation time stamps.
I have commented out a few line in script that was playing with, use to your own liking, but I would advise backing up your data before attempting this.
