Random rng = new Random(DateTime.Now.Day);Random takes an Int as an input; the description is too vague to understand what is meant by "current date time" this implementation only uses the day. See the DateTime Documentation (https://docs.microsoft.com/en-us/dotnet/api/system.datetime?view=netframework-4.8) for more and provide your own implementation.
call random_seed (size=k)
allocate (seed(k))
call date_and_time (values=val)
seed = [(173*i**2+4567,i=1,k)]
m = min(8,k)
seed(1:m) = seed(1:m) + val(m:1:-1)
call random_seed (put=seed)Math.random ()Math.random uses the current time to generate a double floating point number from 0 to 1.
Repeated calls will give different outputs each time.

(setf *random-state* (make-random-state t))This doesn't necessarily use the datetime as there is no portable way to initialize the lisp random-state from an integer.
This is the idiomatic way of getting a random-state that differs with each run.

srand(time());While this is correct, the PHP Manual entry for srand() states: "There is no need to seed the random number generator with srand() or mt_srand() as this is done automatically."
Randomize;srand time;rand = random.Random()the constructor uses the current time if used without arguments.
you could also use the functions of the random module (they are using a shared ``Random`` object which is constructed the first time random is imported

Random.newDon't use time for seeding. Just use the initializer without any arguments.
