You need to tell us what "a long time ago" is.
They wouldn't land at the same time. the rock will land first and quickly because a rock have bigger mass than a feather. A feather is very light, if you ever tried to drop it from some height you could see that it takes very long time to land and it might go away to another place too.
A very long time ago is how ever long you wish to make it there is no set time for a very long time ago.
