Syntactic sugar .fromNow() and .ago() don't work.

```
What steps will reproduce the problem?
1. (2).minutes.fromNow()

What is the expected output?

A time that is two minutes from now.

What do you see instead?

The current time.

What version of the product are you using? On what operating system?

date-en-US.js from svn.

Please provide any additional information below.

The date.js in the downloads section doesn't exhibit this behavior. But it has
a different issue
where Date.parse('12:00 PM') returns null. All my testing is on Safari 4.

Thanks!
