How long does a "corpse" last

If i fall off a mountain or some other Rust related death by my own doing. How long do i have to get back to my gear?

Your corpse doesn’t have the loot, your backpack does. On that note, I have suicided before inside my house because I locked myself in a part (built an extra room and accidently put four walls instead of three and a doorway.) I frantically gathered wood to build some stairs to drop back in then climb out, but by that time (less than five minutes) my backpack was gone. lost like two c4 (attempting to blow out a wall,) countless wooden walls, a couple guns, and tons of ammo. Plus my kevlar armor.

I did mean the back pack of course, Thanks for the feedback.
