NY Harbor spot market trading hours?

What are normal trading hours for spot fuels in NY Harbor (heating oil, gasoline)?

What drives futures prices on Nymex outside these hours?

I know the contract specs. I was asking about spot market.

 

Physical spot market or the front month future?

 

Physical spot market.
