AmbiguousTimeException(ZonedDateTime, ZonedDateTime)
Constructs an instance from the given information.

The earlier of the two occurrences of the local date and time within the time zone.

The later of the two occurrences of the local date and time within the time zone.

The time zone in which the local date and time is ambiguous.


This occurs for transitions where the clock goes backward (usually by an hour). For example, suppose the time zone goes backward at 2am, so the second after 01:59:59 becomes 01:00:00. In that case, times such as 01:30:00 occur twice.

This exception is used to indicate such problems, as they're usually not the same as other ArgumentOutOfRangeException causes, such as entering "15" for a month number.

In theory this isn't calendar-specific; the local value will be ambiguous in this time zone regardless of the calendar used. However, this exception is always created in conjunction with a specific calendar, which leads to a more natural way of examining its information and constructing an error message.
