rcnd --create run_start_time --type time --description "Run start time"
rcnd --create run_end_time --type time --description "Run end time"
rcnd --create is_valid_run_end --type bool --description "True if a run has valid run-end record. False means the run was aborted/crashed at some point"

rcnd --write "value to write" --replace 1000 my_value

For example:

rcnd --write "true" --replace 100 is_valid_run_end
