Newbie Q : Date.now(int)?

On a provision in our system, there is some code e.g.:

const hourly = Date.now(360000);

I can’t find a reference to Date.now with a parameter. JS defines now() it as parameter-less if I am reading the refs correctly.

What does the value do? It was being used to set the gateway inform time.

Thank you, Mark
