This would not necessarily dictate the times worked, just the amount. On site like Upwork it is common practice to have people work 10h/week to start so that work product can be evaluated before spending a tonne with a given contractor, or just to be able to keep up and interact at a reasonable pace. That's not really a legal argument, but it is some precedent that controlling the amount of hours worked is not the same as controlling exactly when they are worked.
