Failure
What a vehicle's failures are measured against.
The choice is not decoration. A fleet with long quiet periods fails a materially different number of times by the clock than by the hours it actually worked, and a subsystem offering only one of the two would be making that modelling decision on the modeller's behalf without saying so.
Entries
Elapsed simulated time, whatever the vehicle was doing. Wall-clock ageing.
Time the vehicle was anything other than idle: moving, blocked, loading, unloading. Hours in service rather than hours on the wall.
Ground covered, in the network's own length units. Wear that goes with mileage.
Tasks the vehicle has finished. Wear that goes with duty cycles.
