That's not really how performance is likely intended to be interpreted here. It's more along the lines of if the client told you "you have to code exactly from X time to Y time using our computer at Z location". At that point you're basically an employee rather than a contractor providing a service/product. Meetings are related to, but not the sole component of performance of work here.
