// iOS does not report its "24-Hour Time" user setting in the API. Instead, it applies
10
// it automatically to NSDateFormatter when used with [NSLocale currentLocale]. It is
11
// essential that [NSLocale currentLocale] is used. Any custom locale, even the one
12
// that's the same as [NSLocale currentLocale] will ignore the 24-hour option (there
13
// must be some internal field that's not exposed to developers).
14
//
15
// Therefore this option behaves differently across Android and iOS. On Android this
16
// setting is exposed standalone, and can therefore be applied to all locales, whether
17
// the "current system locale" or a custom one. On iOS it only applies to the current
18
// system locale. Widget implementors must take this into account in order to provide
19
// platform-idiomatic behavior in their widgets.
