TimeZoneInfo.DisplayName Property

.NET Framework 4

Other Versions

Gets the localized general display name that represents the time zone.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

Syntax

C++

Copy

public string DisplayName { get; }

Property Value

Type: System.String
The time zone's localized general display name.

Remarks

Time zone display names for Windows system time zones follow a fairly standard format. The first portion of the display name is the time zone's base offset from Coordinated Universal Time, which is indicated by the acronym GMT (for Greenwich Mean Time), enclosed in parentheses. For Coordinated Universal Time, the GMT acronym with no offset is enclosed in parentheses. This is followed by a string that identifies the time zone or one or more of the cities, regions, or countries in the time zone. For example:

Copy

(GMT) Greenwich Mean Time : Dublin, Edinburgh, Lisbon, London
(GMT+02:00) Athens, Beirut, Istanbul, Minsk
(GMT-02:00) Mid-Atlantic
(GMT-07:00) Mountain Time (US & Canada)

Examples

The following example retrieves a TimeZoneInfo object that represents the local time zone and outputs its display name, standard time name, and daylight saving time name.

Copy


TimeZoneInfo localZone = TimeZoneInfo.Local;
Console.WriteLine("Local Time Zone ID: {0}", localZone.Id);
Console.WriteLine("   Display Name is: {0}.", localZone.DisplayName);
Console.WriteLine("   Standard name is: {0}.", localZone.StandardName);
Console.WriteLine("   Daylight saving name is: {0}.", localZone.DaylightName);
