Here's how you can do it:Define the function that you want to spawn as a separate process. For example, let's say you want to spawn a process to calculate the factorial of a number: fact(N) -> fact(N, 1). fact(0, Acc) -> Acc; fact(N, Acc) -> fact(N-1, N*Acc).

5 min readIn Erlang, the os:timestamp/0 function can be used to get the current time with microsecond precision. The os:timestamp/0 function returns a tuple in the format {MegaSecs, Secs, MicroSecs}. By extracting the third element (MicroSecs) from the tuple, you can obtain the current time in microseconds.Here's an example code snippet demonstrating how to retrieve the current time in microseconds using os:timestamp/0: Now = os:timestamp(), MicroSecs = element(3, Now).
