Syntax
'Declaration
Public Shared ReadOnly Property Local As TimeZoneInfo

Property Value
Type: System.TimeZoneInfo
A TimeZoneInfo object that represents the local time zone.
Remarks
The local time zone is the time zone on the computer where the code is executing.

|---|
You should access the local time zone through the TimeZoneInfo.Local property rather than assigning the local time zone to a TimeZoneInfo object variable. |
On Windows systems, the TimeZoneInfo object returned by the TimeZoneInfo.Local property reflects the setting of the Automatically adjust clock for daylight saving changes checkbox or the Automatically adjust clock for Daylight Saving Time checkbox in the Control Panel Date and Time application for Windows XP and Windows Vista, respectively. If the checkbox is unchecked, the cached copy of the local time zone contains no daylight saving time information. This means that:
The local time zone's SupportsDaylightSavingTime property returns false.
The local time zone has no ambiguous or invalid times (all calls to IsAmbiguousTime or IsInvalidTime return false).
All calls to IsDaylightSavingTime with individual local times return false.
Version Notes
XNA Framework
When this property is used in the XNA Framework, it throws a NotSupportedException exception.
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.
Dim localZone As TimeZoneInfo = TimeZoneInfo.Local
outputBlock.Text &= "Local Time Zone:" & vbCrLf
outputBlock.Text &= String.Format(" Display Name is: {0}.", localZone.DisplayName) & vbCrLf
outputBlock.Text &= String.Format(" Standard name is: {0}.", localZone.StandardName) & vbCrLf
outputBlock.Text &= String.Format(" Daylight saving name is: {0}.", localZone.DaylightName) & vbCrLf
TimeZoneInfo localZone = TimeZoneInfo.Local;
outputBlock.Text += "Local Time Zone ID:" + "\n";
outputBlock.Text += String.Format(" Display Name is: {0}.", localZone.DisplayName) + "\n";
outputBlock.Text += String.Format(" Standard name is: {0}.", localZone.StandardName) + "\n";
outputBlock.Text += String.Format(" Daylight saving name is: {0}.", localZone.DaylightName) + "\n";
