If you are using this cam as a car dvr, the firmware with 50S/S/C will suit the bill. You do not need a jumbo since the cam is connected to car charger.
I think Diana was confused. There is a firmware (available here) here that has the date stmp in the video, with 20 min. S/S/C/ It's called "recover time". There's also "remove time" which is 20 min S/S/C, and "continuous" with no date, but it has a bug and does not restart a new recording after the mandatory 4GB file limit S/S/C.
