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 } }
