ELAPSED
stackThe ELAPSED
function pushes onto the stack a list containing timing informations. The first element of the list is the timestamp at which
the script was started (in ns). The other elements are the elapsed nanoseconds from the beginning of the script to the end of the execution
of the associated script line.
Timing informations are only collected after a call to TIMINGS
(its line included) and before a call to NOTIMINGS
(its line excluded).
