time(n)                                     Tcl Built-In Commands                                    time(n)



____________________________________________________________________________________________________________

NAME
       time - Time the execution of a script

SYNOPSIS
       time script ?count?
____________________________________________________________________________________________________________


DESCRIPTION
       This  command  will  call the Tcl interpreter count times to evaluate script (or once if count is not
       specified).  It will then return a string of the form
              503 microseconds per iteration
       which indicates the average amount of time required per iteration, in microseconds.  Time is measured
       in elapsed time, not CPU time.

EXAMPLE
       Estimate how long it takes for a simple Tcl for loop to count to a thousand:
              time {
                  for {set i 0} {$i<1000} {incr i} {
                      # empty body
                  }
              }
