Yes, it is less durable than the archive bit in Windows, and so of little use. Most practical apps use the date modified, to control backup and archiving. For casual use, "find -mtime -<days>" is good, but for precise set definition you need something like:
Code:
touch marker_new
sleep 1 # get out of new marker file's second
find ... -newer marker_last ! -newer marker_new | ...
mv -f marker_last marker_done # in case you need a rerun
mv marker_new marker_last

You need to bracket your files with two dates in the past. If you start in th current second, you might miss files modified later in that second. A second is a long time for a modern computer !
