I want to know the command that is executed after a certain period of time.

I guess Pause is a good choice for my purpose. For instance, I tried to let the Mathematica do a job after 5 hours:

Pause[3600*5 (* 3600 seconds is 1 hour *)]
1+1

This code does not work, because after 5 hours I saw Mathematica was still pausing!

I confirmed the above code works if I choose a time around few minutes.

Any ideas would be appreciated, thank you.

    $\begingroup$ I am using version 12.3.1 on Mac OS Big Sur. I saw your screenshot. Your code runs after only 5min. I guess that my PC will be in sleep mode when leaving it for 5 "hours". I expect that I don't have this problem if I turn off the sleep mode. $\endgroup$

  • $\begingroup$ Probably with RunScheduledTask you will have the same problem when the PC will be in sleep mode... $\endgroup$

    $\begingroup$ That 's right. Now, I realized that the problem was not in a specific command in mathematica, but in sleep mode... $\endgroup$

You can use scheduled tasks. Also, they do not hold up processing while waiting to activate : As demonstrated below, x continues to update while the message displays and then disappears.

x = 0;
Dynamic[x]

Module[{},
 If[True,
  message = CreateDialog[TextCell[Style[
      "\n      Your message here.      \n\n", 18]],
    WindowFloating -> True];
  RunScheduledTask[NotebookClose[message], {1.5}]];
 Array[If[Mod[#, 100] == 0, x = #] &, 2000000];]
