While I'm not sure on the status of this as a bug, I would suggest
anyway to use the setDate() and getDate() methods instead. On a date
object, you can call setDate() with an arbitrary value and have the date
automatically adjust to stay consistent. That is, consider this example:
var today:Date = new Date( 2006, 9, 16, 22, 49, 18, 0 );
var result:Date = new Date( 2006, 9, today.getDate() + 16, 22, 49, 18, 0 );
trace( today ); // Mon Oct 16 22:49:18 GMT-0400 2006
trace( result ); // Wed Nov 1 22:49:18 GMT-0500 2006
Since October 32nd doesn't exist, he Date object was smart enough to
know to roll over to November when you try to set a "date" value more
than the number of days in the month. Note in this example, the
timezone changes as well, but thats because of daylight savings time.
As a general rule, if you want to add days to a date, just use setDate(
getDate() + value ).. value can be positive or negative, it doesn't matter.
