Hi Jimmy,
This is described in AudioServerPlugIn.h.
outSampleTime and outHostTime are a couple which tells the HAL what was the Sample position and the System Time when the driver's circular buffer has wrapped.
This couple is used by the HAL's clock to synchronised its input and output heads from the device clock.
Note, in my experience under OSX 10.8 and 10.9, outSeed seems not work as described.
At least, I was not able to use it to tell the HAL that the device time line has changed.
I'm still waiting informations from Apple about it...
