Sean-
Thanks for your reply. Yes, I tried a sample App. (XCode > New Project > Cocoa App. Open Xib in IB. Drag DatePicker into window. Build & debug. AM/PM. Change System Pref to 24 hour clock. Rebuild & debug. Same behavior).
However, I really prefer to specify this outside of the System Preferences anyway. Most of us (in the US) are used to AM/PM clocks (so I want the rest of the computer's apps to work in AM/PM), but for this work related project, the time must be military. In any event, I couldn't force a change of behavior in this code-free (at least by me....) sample app in 10.6.2
Thanks
