DateUtils.getDaysDiff incorrect on DST boundaries

[GoogleCodeExporter]

The following fails:

var start:Date = new Date(2010, 10, 7);
var end:Date = new Date(2010, 10, 8);
Assert.assertEquals(1, DateUtils.getDaysDiff(start, end));

A patch to fix this would be to substitute the getDaysDiff function with:

var startMillis:Number = startDate.getTime();
var endMillis:Number = endDate.getTime();
var dstOffset:Number = (startDate.getTimezoneOffset() - 
endDate.getTimezoneOffset()) * MILLIS_PER_MINUTE;
return Math.ceil((endMillis - startMillis + dstOffset)/ MILLIS_PER_DAY);

Why so complicated? date.valueOf() should work faster/better.
