Rubbing Alcohol in iPhone screen update?

My iPhone only works when it's charging. When I unplug it, it shuts off and the time is stuck on 7:07 PM. December 31, 1969 is what it's also stuck on, too; no matter how many times I have to change it. How do I fix this?

Your battery is dead. What on earth does " Rubbing Alcohol in iPhone screen update" mean?

Connect it to a computer and restore it.
