This is an interface into the motion capture manager. This
interface is passed to plug-ins derived from class MCDeviceBinding. All
methods of this class are implemented by the system.
This method returns the current time at which it is called.
This is an aide for devices where interaction is happening
asynchronously (the MIDI interface is an example of this). The MIDI
motion capture device uses a separate thread to track the MIDI
keyboard. When the user presses a key, the MIDI device plug-in
needs to record which key was pressed and when. It calls this
method to grab the current 3ds Max time at which it happened.
