Time Travel for Fun and Business

I'm currently looking over a cover mechanical, sent via e-mail through my company's neato-keano intranet-based routing system. And I note that it was sent at 8:05 PM on Friday, with a "due back" time of 3:00 PM on the previous day (Thursday).

If I could do that, I very much I doubt I'd be bothering with cover mechanicals for accounting books....
