Mike Tes, Did not find alot on setting date and time for your Drone camera. See if you can do this. If you take a look at your transmitter you can see that it displays the mode you are in (mode 1 and mode 2), camera settings, throttle settings, and battery life. Go into your camera settings and change time and date and save. A couple interesting links to check out below. Good luck.
I hope this helped you out, if so let me know by pressing the helpful button.
