April fools.

You can do this yourself by simply turning your clock back, send the mail and move the clock forward again.

We once had a problem with emails from Japan taking 14 hours or so to be delivered to the NY office.

It was a closed system so there were mail servers on both ends handling everything.

Had one of the guys in the Japan office send emails to my night guy and call him as soon as he hit send.

Night guy waited and sure enough the mail showed up 14 hours later.

Told my night guy to try it again the next day but check the mail queue when he got the call.

Sure enough the mail was sitting in the delivery queue with a scheduled delivery time of 14 hours later.

Japan is 14 hours ahead and the mail server had no idea how to handle mail from "the future" so it just held onto it.
