Nah you shouldnt either.
Maybe it has been bugged then, cause it really worked like that for a period. I experimented heavily to find a way to do what I wanted a few months back (july it seems), and placing a Time More after a condition added a delay of set time, and it worked, cause I can tell a few seconds apart from 3 minutes, especially while trying to maintain a close formation.
Shame if that isnt the case anymore though - for me at least.
And it has been working like that until very recently. I have a small trigger zone attached to a given plane (unit inside moving zone), which triggers a random flag (1 to 4). Each value is then tied to a time more. 30, 60 and 90, while the 4th doesnt exist (want no change/reaction). Now I would fly next to a plane (intercept), close, inside 164 feet, and it would randomly 'react' after a given time, depending on what flag values was picked. Some even as much as 5 minutes, and others just a few seconds. And it worked.
Attached shot of what Im trying to explain.
