JulianDate issues parsing some dates...

[mramato]

I'm not sure why, but the date 11/17/2039 12:00:00 AM UTC produces a JulianDate that is off by one day (November 16 instead of 17). The problem appears to be in computeJulianDateComponents and is most likely a rounding error. I was able to fix the error (by re-porting some Components code) but that caused other tests to start failing (seemingly due to a rounding error in the other direction). The below test should pass, but doesn't.

it('Construct problem dates', function() {
        var expectedDate = new JulianDate(2466109, 43235.0, TimeStandard.TAI);
        var date = JulianDate.fromDate(new Date('11/17/2039 12:00:00 AM UTC'));
        expect(date).toEqual(expectedDate);
    });

@mramato is this still an issue after #1821?

[mramato]

Unfortunately, yes. I have no idea why. I spent some time looking into it and the first "bad" date is 03/01/2034 12:00:00 AM UTC, everything before that works as expected.

Fixed in #2949
