Examples

The following example defines a method named DisplayDateWithTimeZoneName that uses the IsDaylightSavingTime(DateTime) method to determine whether to display a time zone's standard time name or daylight saving time name.

Private Sub DisplayDateWithTimeZoneName(ByVal outputBlock As System.Windows.Controls.TextBlock, ByVal date1 As Date, ByVal timeZone As TimeZoneInfo)
   outputBlock.Text += String.Format("The time is {0:t} on {0:d} {1}", _
                     date1, _
                     IIf(timeZone.IsDaylightSavingTime(date1), _
                         timeZone.DaylightName, timeZone.StandardName)) + vbCrLf
End Sub

private void DisplayDateWithTimeZoneName(System.Windows.Controls.TextBlock outputBlock, 
                                         DateTime date1, TimeZoneInfo timeZone)
{
   outputBlock.Text += String.Format("The time is {0:t} on {0:d} {1}",
                     date1,
                     timeZone.IsDaylightSavingTime(date1) ?
                         timeZone.DaylightName : timeZone.StandardName) + "\n";
}
