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

              503.2 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
                  }
              }
