I'm not sure, but I don't think you can access the computers clock from within FPSC. If you can, I don't know of the command.
While the computers clock is not random, it can be used as a starting point to generate a near-random number by adding the current clock value to a program random. Because it uses fractions of a second after midnight to keep time throughout the day, it is unlikely that any player will do the same thing at exactly the same fraction of a second after midnight as another player, therefore making it nearly-random. Eventually, everything repeats so there is no real random as far as computers are concerned.
Sorry for the long qualification, but some people like to come behind the conversation and make corrections.
