any time a new (as in, not previously existing) file name (including
pathname to the root of the mount point) is introduced on a file system,
attach to that filename a time.

one could argue that the other time stamps are just as arbitrary and
meaningless.  all you have to do is strictly define the behaviour, and
it ceases to be arbitrary.  whether or not it is useless depends on
whether or not you find utility with it.

having a creation time as defined above answers the question "how long
has that filename existed in the filesystem?"  a question that currently
cannot be answered with ffs.  (perhaps lfs can answer it?)
