! !DESCRIPTION:
! Part of Time Manager F90 API wrapper of C++ implemenation
!
! Defines F90 wrapper entry points for corresponding
! C++ class {\tt ESMC\_Time} implementation
!
! See {\tt ../include/ESMC\_Clock.h} for complete description

! ! F90 class type to match C++ Clock class in size only;
! ! all dereferencing within class is performed by C++ implementation

! Note: to mimic ESMF 2.1.0+, AlarmList is maintained
! within ESMF_Clock even though copies of each alarm are
! returned from ESMF_AlarmCreate() at the same time they
! are copied into the AlarmList! This duplication is not
! as hideous as it might be because the ESMF_Alarm type
! has data members that are all POINTERs (thus the horrible
! shallow-copy-masquerading-as-reference-copy hack works).
type(ESMF_Alarm), pointer, dimension(:) :: AlarmList
end type
! Actual public type: this bit allows easy mimic of "deep" ESMF_ClockCreate
! in ESMF 2.1.0+
! NOTE: DO NOT ADD NON-POINTER STATE TO THIS DATA TYPE. It emulates ESMF
! shallow-copy-masquerading-as-reference-copy.
