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
    }
}
