◆ time

type(time_type) mom_ice_shelf::ice_shelf_cs::time

The component's time.

139 type(time_type) :: Time !< The component's time.

◆ time_step

real mom_ice_shelf::ice_shelf_cs::time_step

this is the shortest timestep that the ice shelf sees, and is equal to the forcing timestep (it is passed in when the shelf is initialized - so need to reorganize MOM driver. it will be the prognistic timestep ... maybe.
