!
! 9705, May 97: month number is checked
! 30.74, Nov. 97: Prepared for version with INCLUDE statements
! 40.41, Oct. 04: common blocks replaced by modules, include files removed
!
! 2. Purpose
!
! DTTIME gives time in seconds from a reference day
! it also initialises the reference day
!
! 3. Method
!
! every fourth year is a leap-year, but not the century-years, however
! also leap-years are: year 0, 1000, 2000 etc.
! 1 jan of year 0 is daynumber 1.
!
! 4. Argument variables
!
! INTTIM(1): year
! (2): month
! (3): day
! (4): hour
! (5): minute
! (6): second

!
! 5. PARAMETER VARIABLES
!
! 6. LOCAL VARIABLES
!

! IYRM1 : ??
! IDNOW : ??
! I : ??
! II : ??
!
INTEGER IDYMON(12), IYEAR, IYRM1, IDNOW, I, II
!
! LEAPYR : Whether year in INTTIM(1) is a leapyear
! LOGREF : ??
!
LOGICAL LEAPYR, LOGREF
!
! REFDAY day number of the reference day; the reference time is 0:00
! of the reference day; the first day entered is used as
