Documentation

If you're writing python, and you use "go to definition" on date#strftime you get

    def strftime(self, fmt):
        "Format using strftime()."
        return _wrap_strftime(self, fmt, self.timetuple())

Which is not very helpful. _wrap_strftime is pretty incomprehensible so reading that doesn't help.

If you look up strftime on the docs it also doesn't explain the format. If you click the link to see detailed behaviour you get this wall of reference information which doesn't have just a single example that'll tell 99% of engineers of what their format should look like.

I'm going to put up a PR to fix this.
