 CONT: After the crash when Kelly is resting on the side of a sand  dune and hears two shots behind her, it is still daytime. When the  others take a look, it is nighttime as you can see some stars behind  them in the sky and of course the darkness about them. They seemed  to be eager to go, yet it couldnt have taken them that long to get  up there. When Rodney gets shot its still nighttime, yet when they  bring him back to the plane afterward its like midday.
