Subject: Adding convenience methods per #22
X-Git-Tag: 1.0.1~27
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f5fe9e89c728c5ce6c3c6f41d369d652cdf54dfc;p=thirdparty%2Fmoment.git

Adding convenience methods per #22

Adding `year month date day hour minute second`
Changing internal _date native `Date` object name to `_d` instead of
`date` to avoid collisions with the `_date.fn.date` method.
