ESMF_ClockDestroy Subroutine

      subroutine ESMF_ClockDestroy(clock, keywordEnforcer, rc)
!
! !ARGUMENTS:
      type(ESMF_Clock), intent(inout)          :: clock
      type(ESMF_KeywordEnforcer), optional:: keywordEnforcer ! must use keywords below
      integer,          intent(out),  optional :: rc

! \end{itemize}
!
! !DESCRIPTION:
!     \begin{sloppypar}
!     Releases resources associated with this {\tt ESMF\_Clock}.  This releases
!     the list of associated {\tt ESMF\_Alarm}s (pointers), but not the
!     {\tt ESMF\_Alarm}s themselves; the user must explicitly call
!     {\tt ESMF\_AlarmDestroy()} on each {\tt ESMF\_Alarm} to release its
!     resources.  {\tt ESMF\_ClockDestroy()} and corresponding
!     {\tt ESMF\_AlarmDestroy()}s can be called in either order.
!     \end{sloppypar}
!
!     \begin{sloppypar}
!     If {\tt ESMF\_ClockDestroy()} is called before {\tt ESMF\_AlarmDestroy()},
!     any {\tt ESMF\_Alarm}s that were in the {\tt ESMF\_Clock}'s list will
!     no longer be associated with any {\tt ESMF\_Clock}.  If desired,
!     these "orphaned" {\tt ESMF\_Alarm}s can be associated with a different
!     {\tt ESMF\_Clock} via a call to {\tt ESMF\_AlarmSet(...clock=...)}.
!     \end{sloppypar}
!
!     The arguments are:
!     \begin{description}
!     \item[clock]
!       Release resources associated with this {\tt ESMF\_Clock} and mark the
!       object as invalid.  It is an error to pass this object into any other
!       routines after being destroyed.
!     \item[[rc]]
!       Return code; equals {\tt ESMF\_SUCCESS} if there are no errors.
!     \end{description}
