A colleague needs it to prevent that two users simultaneously create a temporary file. But more important is that he has only 5 positions to store the unique part.

My guess is that he can use the right five positions of sys(2015) and delete the temporary file after a while.

He wants to know the algorithm behind sys(2015).
