   AArrgguummeennttss::

          x: a chron object, a character vector, or a numeric
             vector specifying time. If character, it must be
             in a format recognized by `chron()'. If numeric,
             it specifies Julian dates, i.e., number of days
             since an origin.

        ...: parameters for `chron()'.

   VVaalluuee::

        An object of class `dates' or `times', depending of the
        function called.

        These functions return objects inheriting from dates
        and times, respectively. They call `chron()' if `x'
        does not belong to any of the chronological classes.
