Represents a time zone.
Assembly: mscorlib (in mscorlib.dll)
Thetype exposes the following members.
|Equals(Object)||Determines whether the specified object is equal to the current object. (Inherited from 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.)|
|GetDaylightChanges||Returns the daylight saving time period for a particular year.|
|GetHashCode||Serves as the default hash function. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|GetUtcOffset||Returns the Coordinated Universal Time (UTC) offset for the specified local time.|
|IsDaylightSavingTime(DateTime)||Returns a value indicating whether the specified date and time is within a daylight saving time period.|
|IsDaylightSavingTime(DateTime, DaylightTime)||Returns a value indicating whether the specified date and time is within the specified daylight saving time period.|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ToLocalTime||Returns the local time that corresponds to a specified date and time value.|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
|ToUniversalTime||Returns the Coordinated Universal Time (UTC) that corresponds to a specified time.|
A time zone is a geographical region in which the same standard time is used.
Whenever possible, use the TimeZoneInfo class instead of the class.
You can use the class to retrieve information about the current time zone, and to convert times from local time to Coordinated Universal Time (UTC) or vice versa. However, you cannot use the class to represent time zones other than the local zone or to handle date and time conversions from one time zone to another. For this purpose, use the TimeZoneInfo class. You can use this class to retrieve information on any time zone defined on the local system, to create custom time zones, and to convert times from one time zone to another.
The class supports only a single daylight saving time adjustment rule for the local time zone. As a result, the class can accurately report daylight saving time information or convert between UTC and local time only for the period in which the latest adjustment rule is in effect. In contrast, the TimeZoneInfo class supports multiple adjustment rules, which makes it possible to work with historic time zone data.Notes to Inheritors
In addition to providing implementations for its abstract members (those marked MustOverride in Visual Basic), it is important that classes derived from override the default behavior of the ToLocalTime method. This is because the default behavior of ToLocalTime in the .NET Framework version 2.0 does not depend on a call to GetUtcOffset, as it did in the .NET Framework versions 1.0 and 1.1. For details, see the ToLocalTime method.
