Time travelling movie, a cave I think comedy?

Time travelling movie where the guy has to go to a cave to travel through time. I think it's a comedy but maybe not. I think he gets shot with an arrow and he's got this girl.

This guy might have stole a time travelling device from a guy in a space suit or something

That's all I got right now.

Any ideas?

The movie is Palm Springs. I forgot to mention he got shot in the back with an arrow.

Land of the Lost?

Thanks for the quick replies guys, I'm about to post one more.

The title of the movie is right there I think.

Palm Springs

Thanks, yes I posted that just as all the posts came in, my computer was late to update. Thanks

I misread your post. I thought you were saying it took place in Palm Springs.
