Timezone offset bug

When I hit my site from a +1000 timezone and run the date through a $filter with the Z timezone formatter I get a -1000 timezone.

e.g.

var now = new Date(); // Fri Aug 10 2012 14:00:00 GMT+1000
var created = $filter('date')(now, "yyyy-MM-ddTHH:mm:ss.000Z");

Which equals:

"2012-08-10T14:00:00.000-1000"

I would expect it to equal:

"2012-08-10T14:00:00.000+1000"

If my understanding is not flawed, then this is the method that has the bug.

around line: 9805 (angular.js 1.0.1)

function timeZoneGetter(date) {
    var offset = date.getTimezoneOffset();
    return padNumber(offset / 60, 2) + padNumber(Math.abs(offset % 60), 2);
}

@benpriebe Seems like a bug to me too. Looking at http://www.w3.org/TR/NOTE-datetime it states:

Times are expressed in local time, together with a time zone offset in hours and minutes. A time zone offset of "+hh:mm" indicates that the date/time uses a local time zone which is "hh" hours and "mm" minutes ahead of UTC. A time zone offset of "-hh:mm" indicates that the date/time uses a local time zone which is "hh" hours and "mm" minutes behind UTC.

Definitively a duplicate of #1532

2 issues as far as I can tell:

+/- signs are flipped
+ sign is never added

Going to close this one so we can focus on addressing #1532

fix(date): invert timezone sign and always display sign
