class UIng::DateTimePicker

Overview

A native picker for local calendar and clock fields.

Time values are treated as wall-clock values: the setter copies their displayed date and time fields without converting them to another time zone. Values returned by the getter and callbacks use Time::Location.local. The original instant, offset, and location therefore do not round-trip when they differ from the local time zone.
