The war ended 80 years before the events of RWBY, as far as I know. And we know the color naming rule was made up during the war. I don't know if the length of the war is ever specified, but say, if it lasted 10 years, Ozpin must have been born before that. And he certainly doesn't act like he's 90 years old.
