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

              503.2 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
                  }
              }
