If you call "date" with appropriate arguments, it returns a string in
numeric format, which is then converted to a number when used as argument
to randomseed. For instance, if you call
randomseed(date"%H%M%S")
your seed is a concatenation of the current hour-minutes-seconds (pretty
close to "real" time for random purposes).
