The ostree format intentionally *doesn't* store any timestamps, aside from
a single timestamp on the commit object, but that's not relevant
to the file timestamps.  Instead, everything in the immutable set is 0:

https://bugzilla.gnome.org/show_bug.cgi?id=720363

For /etc which is writable, see https://bugzilla.redhat.com/show_bug.cgi?id=1229160
For /var, ostree itself (almost) never touches it, we rely on systemd-tmpfiles.

One thing that's a bit relevant to this list is that it's now a bug for
tools run in %post to rely on file timestamps to determine whether or
not something changed.   I'm not aware of anything that does today though,
most things use file triggers or just run unconditionally.
