foreach(TimeZoneInfo zone in zones)
{
if (! zone.SupportsDaylightSavingTime)
Console.WriteLine(zone.DisplayName);
}
let zones = TimeZoneInfo.GetSystemTimeZones()
for zone in zones do
if not zone.SupportsDaylightSavingTime then
Console.WriteLine zone.DisplayName
Dim zones As ReadOnlyCollection(Of TimeZoneInfo) = TimeZoneInfo.GetSystemTimeZones()
For Each zone As TimeZoneInfo In zones
If Not zone.SupportsDaylightSavingTime Then _
Console.WriteLine(zone.DisplayName)
Next
Remarks
The value of the SupportsDaylightSavingTime property for the local time zone returned by the TimeZoneInfo.Local property reflects the setting of the Control Panel Date and Time application's checkbox that defines whether the system automatically adjusts for daylight saving time. If it is unchecked, or if no checkbox is displayed for a time zone, the value of this property is false
.
