Window XP notebook seems fine, Im in California so I havent checked my office desktop.
Treo 700w - Verizon - patch installed - changed time but apparently did so by quantum teleporting me to Caracas/La Paz as my location.
HTC TyTN - TMobile - Patch installed (twice) - didnt change, did it manually
HTC SDA - TMobile - totally gobsmacked, thinks I am in Denver and changed all my appointment times as well.
