- *   It is expected that some clock components may not be able to fulfill requests
- *   at exactly the prescribed time. This is acceptable so long as the request is 
- *   fulfilled at least as early as described and not later. This structure provides 
- *   fields the client may use to wait for the remaining time.
- *
- *   The client may use either the nOffset or nWallTimeAtMedia fields to determine the 
- *   wall time until the nMediaTimestamp actually occurs. In the latter case the
- *   client can get a more accurate value for offset by getting the current wall
- *   from the cloc component and subtracting it from nWallTimeAtMedia.
