Local times topic

These are naïve types without time zones that rely on external context to provide meaning. Think of them like a clock or a calendar on a wall. Nobody asks what time zone a wall clock is displaying—it's obvious from the location of the clock and the observer.

Use them when the time zone is obvious from the context, or it would add unnecessary complexity. For example:

• Personal reminders
• Alarm clocks
• Bus schedules

var dt = LocalDateTime(2023, 1, 1, 12, 30);
dt.toString() == '2023-01-01T12:30';
var date = LocalDate(2023, 2, 3);
var time = LocalTime(12, 30, 15);
LocalDateTime.fromParts(date, time) ==
  LocalDateTime(2023, 2, 3, 12, 30, 15);
