IATSC_STT Interface
This topic applies to Update Rollup 2 for Microsoft Windows XP Media Center Edition 2005 and later.
The IATSC_STT interface enables the client to get data from a system time table (STT), which defines the current data and time of day. The IAtscPsipParser::GetSTT method returns a pointer to this interface.
In addition to the methods inherited from IUnknown, the IATSC_STT interface exposes the following methods.
| Method | Description |
| GetCountOfTableDescriptors | Returns the number of descriptors in the STT. |
| GetDaylightSavings | Returns the Daylight Savings Time Control bytes. |
| GetGpsUtcOffset | Returns the offset between GPS time and UTC. |
| GetProtocolVersion | Returns the protocol version of the table. |
| GetSystemTime | Returns the current system time. |
| GetTableDescriptorByIndex | Returns a descriptor for the STT. |
| GetTableDescriptorByTag | Searches the STT for a descriptor with the specified descriptor tag. |
| Initialize | Initializes the object. |
