Provides information about a specific time change, such as the change from daylight saving time to standard time or vice versa, in a particular time zone.
Assembly: mscorlib (in mscorlib.dll)
Thetype exposes the following members.
|Day||Gets the day on which the time change occurs.|
|DayOfWeek||Gets the day of the week on which the time change occurs.|
|IsFixedDateRule||Gets a value indicating whether the time change occurs at a fixed date and time (such as November 1) or a floating date and time (such as the last Sunday of October).|
|Month||Gets the month in which the time change occurs.|
|TimeOfDay||Gets the hour, minute, and second at which the time change occurs.|
|Week||Gets the week of the month in which a time change occurs.|
|CreateFixedDateRule||Defines a time change that uses a fixed-date rule.|
|CreateFloatingDateRule||Defines a time change that uses a floating-date rule.|
|Equals(Object)||Determines whether an object has identical values to the current object. (Overrides ValueType.Equals(Object).)|
|Equals(TimeZoneInfo.TransitionTime)||Determines whether the current object has identical values to a second object.|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Serves as a hash function for hashing algorithms and data structures such as hash tables. (Overrides ValueType.GetHashCode().)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ToString||Returns the fully qualified type name of this instance. (Inherited from ValueType.)|
You can use the structure to indicate when a transition from standard time to daylight saving time, or from daylight saving time back to standard time, occurs. This structure supports both fixed-date rules and floating-date rules. Use fixed-date rules for time transitions that occur on a specific day of a specific month (such as 2:00 A.M. on November 3). Use floating-date rules for time transitions that occur on a specific day of a specific week of a specific month (such as 2:00 A.M. on the first Sunday of November).
An instance of the structure is immutable. Once an object has been created, its values cannot be modified.
A object can be created by calling the static (Shared in Visual Basic) CreateFixedDateRule and CreateFloatingDateRule methods to create a fixed or floating-date rule, respectively. The starting and ending objects are then supplied as parameters to the CreateAdjustmentRule method to create a new adjustment rule that includes this transition time information.
The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: MayLeakOnAbort. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.
