My point exactly.  Even in an interpreter, 1ms is a looong time these  
days.  And floats are no longer expensive.

Adding something like would make optimization easier for  
implementers (might translate to only a few instructions on a decent  
architecture, e.g., scale the cycle-count register by the system  
clock frequency).
