Comment 2 for bug 591139

Confirmed. If I manually enter a date that is too high (as a negative number), the controller will start changing the date automatically. When the date is -8895, it won't go lower when you click on the arrow to decrease the year.

 Further, if you try to change the month ( in this case 2), clicking the down button has no effect. Clicking the up button changes the month to 4, and clicking it up a second time causes very strange behavior where the date changes itself, and it end up as -8879/2/0.

Not sure if the bug is with the date code, or the controller.
