StandardName Specifies a null-terminated string associated with standard time on this operating system. This string is not used by the operating system, so anything stored there by using the SetTimeZoneInformation function is returned unchanged by the GetTimeZoneInformation function. This string can be empty. Local time translations done during the standard-time range are relative to the supplied StandardBias value. This member supports two date formats.
Absolute format specifies an exact date and time when standard time begins.
StandardBias Specifies a bias value to be used during local time translations that occur during standard time. This member is ignored if a value for the StandardDate member is not supplied. This value is added to the value of the Bias member to form the bias used during standard time. In most time zones, the value of this member is zero. DaylightName Specifies a null-terminated string associated with daylight time on this operating system.
