is there a way of stabilizing the DELAY

[secs]

Hi all.

As in a previous post I mentioned the DELAY comand is all over the place. Sometimes the same delay command takes 5 seconds and the next time it may be minutes.

Has anyone got an idea on how I can make it consistant? I don't care if the numbers and minutes etc don't correspond, I just want say a delay of 5 minutes each time the DELAY command is called with the same number as its parameter
