What's that mean?
Dakr Knight Returns was written as a "What If" or, to use the old adage, an "Elseworlds before there was an Elseworlds". Year One was the beginning of Batman's in-conitnuity soft reboot after the Crisis. Granted both were written using Miller's take on the character (since he was the writer of both) but they are not connected except perhaps in Miller's mind.
And sorry, but All-Stars is *not* the same "DKR Universe"... either. Frank's stuff stand on their own, each seperate... if there's any overarcing continuity, it's a jumbled mess that contradicts itself constantly.
>>and recently Batman is 24 in All-Star and has been going for a year.>>
Exactly. All Stars contradicts Year One. And in DKR Batman says Dick coined the term "Batmobile", but in All Stars, Batman calls the car a Batmobile when Dick asks what it is. So each story contradicts another, thus they are not the same Universe.
>>In regular continuity Batman meets Robin in the middle of the second year or so (Dark Victory)>>
If you actually read Year One, Long Halloween, and Dark Victory, with careful attention to the dates... Bruce actually meets Dick in Year Five! It's probably the best example of the Loeb/Sale Batman stories being out of continuity. Yes, they were references in Hush, which is definitely In, but the timeline is internally inconsistent.
Miller and Loeb/Sale Timeline:

According to Miller himself on an interview at Newsarama, he always writes for the DKR universe, and yeah, he's contradicted himself, but so what? In the long run, it doesn't matter. DC adopted Year One as continuity, but with reboots and whatnot, not everything stays constant. Comic time is fluid, so putting actual dates to it is pointless, especially so soon after a reboot.
