There will be two main time steps are stored in the PAM coupler. These are set via YAML

  1. gcm_physics_dt: GCM physics time step
  2. crm_dt: PAM's physics time step

The dynamical cores will handle their own time steps. There are also two different elapsed times that are tracked by PAM and updated in the coupler:

  1. current_date_and_time: The current data and time of the CRM physics
  2. crm_elapsed_time: The elapsed time for the current GCM physics time step \in [0,gcm_physics_dt]
