The older AppKit API supports seconds in its Date Picker, but they’ve been dropped from its SwiftUI successor. There are many other signs our Macs are moving to less precise time. Is this intentional, to reverse our slavery to time?
NSDatePicker
When a “fixed” formatting string proves anything but fixed, then breaks without warning or even mention in a release note.
How Apple made changes to Foundation routines which format dates and times which can break their formatting when in 12-hour clock mode.
Why couldn’t a user specify times before 0100 and after 1300, when the DatePicker worked fine using the 24-hour clock?
