TimeZone::DaylightName Property
Visual Studio 2010
Gets the daylight saving time zone name.
Assembly: mscorlib (in mscorlib.dll)
If daylight saving time is not used in the time zone, an empty string ("") is returned.
The DaylightName property corresponds to the TimeZoneInfo::DaylightName property. Whenever possible, use the TimeZoneInfo::DaylightName property.
The following example references and displays the DaylightName property of the current time zone.
// Example of selected TimeZone class elements. using namespace System; using namespace System::Globalization; int main() { String^ dataFmt = "{0,-30}{1}"; String^ timeFmt = "{0,-30}{1:yyyy-MM-dd HH:mm}"; Console::WriteLine( "This example of selected TimeZone class " "elements generates the following \n" "output, which varies depending on the " "time zone in which it is run.\n" ); // Get the local time zone and the current local time and year. TimeZone^ localZone = TimeZone::CurrentTimeZone; DateTime currentDate = DateTime::Now; int currentYear = currentDate.Year; // Display the names for standard time and daylight saving // time for the local time zone. Console::WriteLine( dataFmt, "Standard time name:", localZone->StandardName ); Console::WriteLine( dataFmt, "Daylight saving time name:", localZone->DaylightName ); // Display the current date and time and show if they occur // in daylight saving time. Console::WriteLine( String::Concat( "\n", timeFmt ), "Current date and time:", currentDate ); Console::WriteLine( dataFmt, "Daylight saving time?", localZone->IsDaylightSavingTime( currentDate ) ); // Get the current Coordinated Universal Time (UTC) and UTC // offset. DateTime currentUTC = localZone->ToUniversalTime( currentDate ); TimeSpan currentOffset = localZone->GetUtcOffset( currentDate ); Console::WriteLine( timeFmt, "Coordinated Universal Time:", currentUTC ); Console::WriteLine( dataFmt, "UTC offset:", currentOffset ); // Get the DaylightTime object for the current year. DaylightTime^ daylight = localZone->GetDaylightChanges( currentYear ); // Display the daylight saving time range for the current year. Console::WriteLine( "\nDaylight saving time for year {0}:", currentYear ); Console::WriteLine( "{0:yyyy-MM-dd HH:mm} to " "{1:yyyy-MM-dd HH:mm}, delta: {2}", daylight->Start, daylight->End, daylight->Delta ); } /* This example of selected TimeZone class elements generates the following output, which varies depending on the time zone in which it is run.
