ESMF_TimeSyncToRealTime Subroutine

      subroutine ESMF_TimeSyncToRealTime(time, keywordEnforcer, rc)
!
! !ARGUMENTS:
      type(ESMF_Time), intent(inout) :: time
      type(ESMF_KeywordEnforcer), optional:: keywordEnforcer ! must use keywords below
      integer, intent(out), optional :: rc

! !STATUS:
! \begin{itemize}
! \item\apiStatusCompatibleVersion{5.2.0r}
! \end{itemize}
!
! !DESCRIPTION:
!     Gets the system real time (wall clock time), and returns it as an
!     {\tt ESMF\_Time}.  Accurate to the nearest second.
!
!     The arguments are:
!     \begin{description}
!     \item[time]
!          The object instance to receive the real time.
!     \item[{[rc]}]
!          Return code; equals {\tt ESMF\_SUCCESS} if there are no errors.
!     \end{description}
