Big Blue has released some java patches and has a corrective fix available for AIX that takes care of it.
Trouble is, there are folks who aren't smart enough to RTFM when applying the fixes, let alone plan for change. That's why I make an obscene amount of money. You should have seen the sturm and drang when .au went to the modified DST change earlier than the rest of the planet last year because of the Commonwealth Games. Much ado about nothing.
On my Winderz partition here at home, I'm going to let my atomic clock synch program handle anything that I don't take care of manually.

Rabbit.
