| I think we have to recognize that there are multiple concepts of time.
The common-sense concept of time is the flow of events (which I am sure must quickly become a circular definition).
In some versions of modern physics, time is a discrete component of spacetime. That is, both space and time are granular - divided up into discrete quanta. This concept provides a neat way of explaining the phenomenon known as time dilation.
However, there is no reason to assume that events cannot occur outside of spacetime. Indeed, if our universe began with the big bang, then (unless you believe in acausality) there must exist events outside of our timestream. How else could the big bang have been initiated to begin with?
Thus, we could well have multiple (nested) dimensions of time. In order for such a system to be stable, the inner dimension of time would have to have a variety of rules by which it operates.
