!*    Real time related variables (updated in UPDTIM)

!     NINDAT : run initial date in the form AAAAMMDD
!     NSSSSS : initial time in seconds (e.g. for 12h, 43200)
!     RTIMST : ABSOLUTE TIME OF THE MODEL AT START

!     NSTADD : NUMBER OF DAYS SINCE START OF THE MODEL
!     NSTASS : NUMBER OF SECONDS since start of model modulo(86400)
!     RSTATI : NUMBER OF SECONDS SINCE START OF THE MODEL
!     RTIMTR : ABSOLUTE TIME OF THE MODEL

!     RHGMT  : GMT TIME OF THE MODEL  (BETWEEN 0 AND 86400)
