Usage
DateTimeInput when the workflow commits a specific moment: a callback time, an appointment. Use DateRangeInput when the span is days only, or days and times together.
The date-and-time range matches ui-calendar's AdvancedDateTimeRangePicker: a read-only trigger that shows formatted dates only (no times or zone label on the trigger), Before, After, and Between across the top, the range calendar, From and To time fields under the calendar (defaulting to 00:00 and 23:59 in Between), and Reset and Apply on the footer. Pass modeLabels, modeSelectLabel, applyLabel, and resetLabel for that strip, and set type to DateRangeInputType.DateTime with timeSegmentLabels and timeFieldLabels. timeZone applies to panel times and committed instants, not to trigger copy.
TimeInput with range when the day is already known and only the clock window changes.
