Deletion of Timeline of Batman

Comment: WP:NOR and  a plot summary. The idea of an absolute timeline for a DC character is ridiculous, as adherence to such a timeline, if it exists, is never a concern for writers. Also, where are the sources for exact years? Where is the source of Jason Todd becoming robin and dying in the same year
