# Enum Class ZoneOffsetTransitionRule.TimeDefinition

java.lang.Object
java.lang.Enum<ZoneOffsetTransitionRule.TimeDefinition>
java.time.zone.ZoneOffsetTransitionRule.TimeDefinition

All Implemented Interfaces:
  `Serializable, Comparable<ZoneOffsetTransitionRule.TimeDefinition>, Constable`

Enclosing class:
  `ZoneOffsetTransitionRule`

public static enum ZoneOffsetTransitionRule.TimeDefinition extends Enum<ZoneOffsetTransitionRule.TimeDefinition>
A definition of the way a local time can be converted to the actual transition date-time.

Time zone rules are expressed in one of three ways:

- Relative to UTC
- Relative to the standard offset in force
- Relative to the wall offset (what you would see on a clock on the wall)

Since:
  1.8

- ## Enum Constant Details

  - ### UTC

    public static final ZoneOffsetTransitionRule.TimeDefinition UTC
    The local date-time is expressed in terms of the UTC offset.

  - ### WALL

    public static final ZoneOffsetTransitionRule.TimeDefinition WALL
    The local date-time is expressed in terms of the wall offset.

  - ### STANDARD

    public static final ZoneOffsetTransitionRule.TimeDefinition STANDARD
    The local date-time is expressed in terms of the standard offset.

- ## Method Details

  - ### values

    public static ZoneOffsetTransitionRule.TimeDefinition[] values()
    Returns an array containing the constants of this enum class, in the order they are declared.
    Returns:
      an array containing the constants of this enum class, in the order they are declared

  - ### valueOf

    public static ZoneOffsetTransitionRule.TimeDefinition valueOf(String name)
    Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
    Parameters:
      `name` - the name of the enum constant to be returned.
    Returns:
      the enum constant with the specified name
    Throws:
      `IllegalArgumentException` - if this enum class has no constant with the specified name
      `NullPointerException` - if the argument is null

  - ### createDateTime

    public LocalDateTime createDateTime(LocalDateTime dateTime, ZoneOffset standardOffset, ZoneOffset wallOffset)
    Converts the specified local date-time to the local date-time actually seen on a wall clock.

    This method converts using the type of this enum. The output is defined relative to the 'before' offset of the transition.

    The UTC type uses the UTC offset. The STANDARD type uses the standard offset. The WALL type returns the input date-time. The result is intended for use with the wall-offset.

    Parameters:
      `dateTime` - the local date-time, not null
      `standardOffset` - the standard offset, not null
      `wallOffset` - the wall offset, not null
    Returns:
      the date-time relative to the wall/before offset, not null
