Delegate SkippedTimeResolver

Resolves a LocalDateTime to a ZonedDateTime in the situation where the requested local time does not exist, due to clocks moving forward in a time zone transition (usually due to a spring daylight saving transition).

Syntax

public delegate ZonedDateTime SkippedTimeResolver(LocalDateTime localDateTime, DateTimeZone zone, ZoneInterval intervalBefore, ZoneInterval intervalAfter);

Parameters

Type	Name	Description
LocalDateTime	localDateTime	The local date and time to map to the given time zone
DateTimeZone	zone	The target time zone
ZoneInterval	intervalBefore	The zone interval directly before the target local date and time would have occurred
ZoneInterval	intervalAfter	The zone interval directly after the target local date and time would have occurred

Returns

Type	Description
ZonedDateTime	A ZonedDateTime in the target time zone,

Remarks

The returned value will necessarily represent a different local date and time to the target one, but the exact form of mapping is up to the delegate implementation. For example, it could return a value as close to the target local date and time as possible, or the time immediately after the transition. Alternatively, it can throw a SkippedTimeException to implement a policy of "reject skipped times."

See the Resolvers class for predefined implementations.

Implementations of this delegate can reasonably assume that the target local date and time really is skipped; the behaviour when the local date and time can be directly mapped into the target time zone is undefined.
