Time input

ui.TimeInput creates a field of the time of day of a *time.Time, in the hour cycle of the user's regional formats (Context.Region): 15:04, or 3:04 PM, whose hours, minutes and half of the day each take the keyboard focus, as the segments of AppKit's date picker: Up and Down step the one with the focus round the clock, digits typed set it, going on to the minutes once the hours are typed, the first letter of AM or PM (or of the language's names of them) chooses the half of the day, and Left and Right move between them. The names of the halves of the day and their place are the window's language's: 下午3:04 in Chinese, with the half first. Changed reports a new time, which keeps the date and the location of the value.

ui.TimeInput(c, &app.alarm).Label("Alarm")

A click on the hours or the minutes gives them the focus. With a date input, the two edit one time.Time.
