If so, I don't think so. The template returned from this method uses 'a' as a place holder for AM/PM. e.g. It might return the string 'h a' as it does by default for the English/US locale on my system, and a is always lower case. This is described here http://www.unicode.org/reports/tr35/tr35-31/tr35-dates.html#Date_Format_Patterns See the 'period' field in the Date Field Symbol Table and section 8.2 for my justification. > > It seems to me you have two choices.

Yea, I was considering just making it an app local preference but that strikes me as crude. Ideally speaking, at best an appropriate preference for my app could be 'Override System 24 hr time preference' or something akin. But, I might have to settle for that... > _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
