How to display DateTime with an abbreviated Time Zone?

Here’s my quick hack method I just made to work around this.

public static String TimeZoneName(DateTime dt)
{
    String sName = TimeZone.CurrentTimeZone.IsDaylightSavingTime(dt) 
        ? TimeZone.CurrentTimeZone.DaylightName 
        : TimeZone.CurrentTimeZone.StandardName;

    String sNewName = "";
    String[] sSplit = sName.Split(new char[]{' '});
    foreach (String s in sSplit)
        if (s.Length >= 1)
            sNewName += s.Substring(0, 1);

    return sNewName;
}
