``Convenient''?  IMHO, you need to be a CS graduate just to understand
it.  Take a look at the Yacc parser summoned for the implementation of
the "--date" option, or at the node in fileutils.info that documents

Even the simpler "-t TIME" option's format is not easy to get right: I
always confuse the traditional (and insane) MMDDhhmm[YY] format with
the newer [[CC]YY]MMDDhhmm[.ss] format and need to consult the docs to
be sure I don't screw up my time stamps.

I wish Emacs had something more human-friendly, perhaps accessible via
mouse clicks on the date/time fields of the Dired display or some such.
