Yes an no. Writing the last read page to en external file works only on the same computer. If you copy/move it to another compter he dosn't know somthing of it.

Changing the file date should only be used for a serious file modification.

How do you whand do that? That's a function of the operating system. Every modern OS safes the last time of reading al file. And of course, when a program writes something into al file the file date must be changed.
Some OS, for example Unix/Linux, change the file date if a file ist copied. Not changed, only using the cp-commad of the OS.
