Why?

Reason for asking is there are a couple of reasons why one does not want to modify the atime. The 'best' / 'correct' solution differs for each case.

Maybe you don't want to incurr the update-penalty? (mount filesystem with noatime/relatime).

Maybe you want to check whether the content has changed? (rsync uses the inode metadata to do this)

Maybe you want to see 'true' access/read attempts via atime? (read and restore atime)

Or maybe something completely different?
