How are hours on a hour meter calculated?

I have a little over 1000 hours on the hour meter of my Troy-bilt. How are hours calculated? Strickly running time? I assumed it had something to do with RPM. Does it have anything to do with the speed the engine is running at? The faster the engine is running the faster the hours add up?

It's a rainy day question on a rainy Sunday morning. Thanks.

Hour meters reflect running time hours without regard to engine speed.

Many hour meters on riding mowers count the time that the key is in the hour position, regardless of whether the engine is running or not. If the key was turned on and left on say for a week, then your hour meter would show 168 hours even though the engine was not running. There are meters that operate off of a running engine only and do not count other time.
