the exact same number ?
so they are not really random...

There could be a pattern for the random number madness. Something similar to this:
Computer takes pi and divides by 7 and 2/5. It then stores the third digit.
Then the computer takes the fourth digit of 7/23 (a non-repeating, non-terminating decimal).
Those two numbers multiplied together is the first digit of your random number.

Then a similar process is repeated for the second, third, etc. If the number generated was larger or smaller than your parameters, it would simply divide or multiply by 10, 100, 1000, etc. Or maybe it would divide or multiply by 49/23...
Again, this is only speculation.

The clock idea sounds feasable, but I see flaws. In Visual Basic (my only programming language that exceeds amateur) there is a function to generate random numbers. These random numbers are predetermined, but there is no pattern. I would assume they come from some fraction such as 7/23 (only much more complex) or some variation of pi. However, there is another function, that, when combined with the original, will randomize the random numbers. They will not be predetermined. By no means have I ever gotten the same numbers on different tests based upon time. Thus, I would have to assume that the random numbers are not based upon any clock.
