The GPS18 LVC already sends out quite a long pulse, 200msec IIRC, so no stretching should be required. You can program the length. Putting an LED (with a 470 ohm resistor) between the PPS output and ground should show approximately what the pulse length is. With 200ms I can clear see the start and end of the pulse as two distinct events.
