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
}
}
