Oh, "j" works on iOS if you pass it to -dateFormatFromTemplate:options:locale:, but only if you pass [NSLocale currentLocale] and not nil.

Changing the clock has no effect, but I haven't verified that changing the time format does. -- Rick On Feb 23, 2012, at 11:37 , Dave DeLong wrote: > > On Feb 23, 2012, at 8:21 AM, Kyle Sluder wrote: > >> On Feb 22, 2012, at 10:50 PM, Rick Mann <rm...@latencyzero.com> wrote: >> >>> I have a need to format times as either >>> >>> 24:mm >>> >>> or >>> >>> 12:mm >>> am >>> >>> That is, if the user prefers a 24-hour clock, I want it to appear on a >>> single line.
