! ABSTRACT: THIS SUBPROGRAM RETURNS THE LOCAL DATE AND TIME
!   IN THE NCEP ABSOLUTE DATE AND TIME DATA STRUCTURE.
!
! PROGRAM HISTORY LOG:
!   98-01-05  MARK IREDELL
! 1999-04-28  Gilbert         - added a patch to check for the proper
!                               UTC offset.  Needed until the IBM bug
!                               in date_and_time is fixed.  The patch
!                               can then be removed.  See comments in
!                               the section blocked with "&&&&&&&&&&&".
! 1999-08-12  Gilbert         - Changed so that czone variable is saved
!                               and the system call is only done for
!                               first invocation of this routine.
