On stretch system, man mount has under "FILESYSTEM-INDEPENDENT MOUNT
OPTIONS" a section about relatime:
Since Linux 2.6.30, the kernel defaults to the behavior
provided by this option (unless noatime was specified), and
the strictatime option is required to obtain traditional
semantics. In addition, since Linux 2.6.30, the file's last
access time is always updated if it is more than 1 day old.

I've used noatime in fstab for a long time that way. Check man mount and
see what wheezy says, not sure about the history there...
