A conformant clock component, designed to be compatible with a
standard clock component. It currently supports 6 output clock ports.
| Port | Index | Notes | 
| 80  81  82  83  84  85 | OMX_IndexParamPortDefinition | The port definition can be used to connect each port to a clock port
  on another component. | 
| OMX_IndexParamOtherPortFormat | This param is used to confirm that this port supports clock messages. | 
| OMX_IndexConfigTimeScale | We support setting the timescale to achieve slow motion, fast forward,
  paused, and rewind playback. To achieve rewind and fast forward, note the
  extra playmode config in the read_media. | 
| OMX_IndexConfigTimeClockState | Query / set current clock state. | 
| OMX_IndexConfigTimeCurrentWallTime | Query current wall time. | 
| OMX_IndexConfigTimeActiveRefClock | Query / set the active reference clock. | 
| OMX_IndexConfigTimeCurrentMediaTime | Query current media time. | 
| OMX_IndexConfigTimeClientStartTime | Set the start time of a client stream, typically used by
  a tunneled component. | 
| OMX_IndexConfigTimeInvalidStartTime | Notification that a client will not be sending a start time. | 
| OMX_IndexConfigTimeCurrentAudioReference | Set the instantaneous audio reference clock value.  Time values
  received are filtered to remove jitter. | 
| OMX_IndexConfigTimeCurrentVideoReference | Set the instantaneous video reference clock value. | 
| OMX_IndexConfigTimeMediaTimeRequest | Make a media time request. | 
| OMX_IndexConfigBrcmClockMissCount | Return a count of the number of media time requests that were missed, because they
  arrived too late (after the requested time). | 
|  | OMX_IndexConfigSingleStep | Advance a paused clock through the next set of requested media times. | 
| OMX_IndexConfigClockAdjustment | Get the total amount that the clock media time has shifted due to
  clock reference time updates since the clock started running. | 
| OMX_IndexConfigLatencyTarget | Query / set the filter values used when tracking offset between media time
  and reference clock source by applying small changes to media time speed. |
