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 isn't  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
                  }
              }
