Physical laws present to us, (or would present to us in ideal case), the necessary relation (necessary for any measured system in this world) between different values we measure on a system.
Number is ratio, and measurement is applying of such ratio to certain quality of the system by comparing to the quality which is taken as unit. In such way through measurement, we abstract number from the physical system.
Time is merely one of those values which are measured.
Can we say then that physical laws are not the thing that give life to universe? They just say that for any system in the universe, the values will fall into certain relation.
