'date created'
'date modified'
'date accessed'
are three of many more flags NTFS (and ext2/3) have
all you need to do is stop using those fluffy huge icons when browsing your files, and start using 'details' view
in your explorer (or any other file manger for that matter...) views -> details.
if the columns mentioned dont show up, right click in the columns header and add the ones you want.
you can sort by date created, or date modified.
date created will get reset upon copy/move/extract but date modified wont.
