This is usually done somewhere deep in the filesystem, but yes.  It is
not done by the application (neither value is normally set by the
app).

This is not clear.  Most directory listings for normal filesystems
don't include the creation time, but it remains available.  Do you not
consider it reasonable to show the creation time?  One thing that can
be interesting is determining whether an object has been maintained
since the initial creation; the creation date allows that.  (So would
some mark, possibly an icon, indicating that the object has been
modified since the initial creation.)

This is a nice property.
