What we call time is just our measurement of things such as the movement of hands on a clock or the movement of a football on a field

 

      No, time is an integral part of space itself. What Hawking is talking about is how we measure what we call time. This concept of time is ours and ours alone. God's time is His time and space-time is a measurement in a direction that is orthogonal (at right angle) to the three dimensions in which we exist. http://www.cartoonstock.com/lowres/sma0052l.jpg
