Agreed, that two pseudo-random numbers based on the same seed will produce the same output, but when the seed numbers are based on a time clock, (and the start trigger time is based on a human input like pressing the "go" button, or heck, even what time of day they choose to turn on the computer) you'll never be able to predict the output and it'll be different every time.

This may seem like a good idea, but in my line of work, anyone who uses this method to generate a random number is asking for trouble. This is one of the easiest to break. We have a selection of exploits to break TCP sequence numbers so we can hijack sessions - most of which depend on system time as a seed.

See here for an amusing demonstration of the lack of randomness in computers.
