TIME _ _ _ _ _ _ _ _ _ _ _ _ switch

When time is on, the system time used in executing each REDUCE statement is printed after the answer is printed.

examples:

on time; 

  Time: 4940 ms 


df(sin(x**2 + y),y); 

            2
  COS(X  + Y )
  Time: 180 ms


solve(x**2 - 6*y,x); 

  {X= - SQRT(Y)*SQRT(6),
   X=SQRT(Y)*SQRT(6)}
  Time: 320 ms

When time is first turned on, the time since the beginnin g of the REDUCE session is printed. After that, the time used in computation, (usually in milliseconds, though this is system dependent) is printed after the results of each command. Idle time or time spent typing in commands is not counted. If time is turned off, the first reading after it is turned on again gives the time elapsed since it was turned off. The time printed is CPU or wall clock time, depending on the system.
