[QUOTE="spiney, post: 275857, member: 192438"] ......er, wozzat? Hang on, let me have a shower and some breakfast ........ ........ that's better. As PaulR says, there was no "time" before the universe (Hawking also has a topological theory that there's no "beginning", since the topology becomes different around the big band "event"). Time is a property OF the universe - closely tied up with thermodynamics, entropy, statistical mechanics, etc - and probably would not otherwise exist. It is certainly not something "imposed from outside". (If you think you can "imagine" a completely empty universe - but with time still passing - then think again, what's the flaw here?). Don't forget, what you humans call time (oops!) is entirely subjective, clocks tick at different rates for observers in relative motion (special relativity). There's also the possibility that subjective time is entirely a "human construct", ie, Kant's "transcendental" pre-condition for any perceptions at all to take place!
