Well, "in the real world"*, time can be warped and is very subjective depending on where you are in space. When you think about it, the Flashes fuck up the time-stream constantly, just by existing. Then there's all these weird space gods whose technology can rip moments from each other's arms with effectiveness rivaling American border patrols. :ou Most people with an in-character perspective would probably struggle to date each days events anyhow. It really doesn't seem like a stretch for me to say that time is kinda murky for superheroes who aren't investigating something. It doesn't seem contrived from my perspective. There's no way that there's enough time in Batman's life for all the adventures that have been written for him in any given continuity, really, especially when you consider how often individual missions can involve spending multiple weeks or months. *I don't believe in [i]the[/i] real world.
