  NameDescription
Public methodSupported by the XNA FrameworkEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected methodSupported by the XNA FrameworkFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodSupported by the XNA FrameworkGetDaylightChangesReturns the daylight saving time period for a particular year.
Public methodSupported by the XNA FrameworkGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodSupported by the XNA FrameworkGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodSupported by the XNA FrameworkGetUtcOffsetReturns the Coordinated Universal Time (UTC) offset for the specified local time.
Public methodSupported by the XNA FrameworkIsDaylightSavingTime(DateTime)Returns a value indicating whether the specified date and time is within a daylight saving time period.
Public methodStatic memberSupported by the XNA FrameworkIsDaylightSavingTime(DateTime, DaylightTime)Returns a value indicating whether the specified date and time is within the specified daylight saving time period.
Protected methodSupported by the XNA FrameworkMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodSupported by the XNA FrameworkToLocalTimeReturns the local time that corresponds to a specified date and time value.
Public methodSupported by the XNA FrameworkToStringReturns a string that represents the current object. (Inherited from Object.)
Public methodSupported by the XNA FrameworkToUniversalTimeReturns 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.

Important noteImportant

Whenever possible, use the TimeZoneInfo class instead of the TimeZone class.

You can use the TimeZone 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 TimeZone 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 TimeZone class supports only a single daylight saving time adjustment rule for the local time zone. As a result, the TimeZone 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 TimeZone 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.

The following example references and displays selected TimeZone class elements.
