-    The `walltime` must be set to be long enough that the PBS job can complete. The model usually runs a single year in 90 minutes or less, but the `walltime` for a single model run is set to `2:30:00` out of an abundance of caution to make sure the model has time to run when there are occasional slower runs for unpredicatable reasons. When setting `runspersub > 1` the `walltime` doesn't need to be a simple multiple of `2:30:00` because it is highly unlikely that there will be multiple anomalously slow runs per submit.

 When debugging changes to a model, it is common to reduce the run length to minimise resource consumption and return faster feedback on changes. In order to run the model for a single month, the `runtime` can be changed to
