Q: Random[]

I am constructing a Monte-Carlo simulator in Mathematica for an x-ray polarimeter we are proposing for NASA's Explorer program. I have 2 questions about Random[]: 1. What is its period? This affects how large a Monte-Carlo I can run before losing independence of trials. 2. I understand it gets its seed from the clock. When debugging Monte-Carlo code, I like to set the seed so I can repeat runs. Is this possible for Random[], and if so how? (The seed initiates the sequence of psuedo-random numbers.)
