I'd prefer a threshold time:  If the execution takes less than the threshold, nothing is printed.

Personally, I'd set the threshold to 5 seconds in my profile (if I had one), and this would make sense as a global default too.

I used to do something like this in my Unix shell profile.

Sometimes you don't know how long a command will take, but you don't want a timing report for every piddling command.

Having threshold reporting logic gives you the right mix of information and concision.
