Gmail New Feature Lets You Send Email Into The Past

Introducing Gmail Custom Time. Be on time. Every time.
How do I use it? Just click "Set custom time" from the Compose view. Any email you send to the past appears in the proper chronological order in your recipient's inbox. You can opt for it to show up read or unread by selecting the appropriate option.
Is there a limit to how far back I can send email? Yes. You'll only be able to send email back until April 1, 2004, the day we launched Gmail.
How does it work? Gmail utilizes an e-flux capacitor to resolve issues of causality (see Grandfather Paradox).
