scale $f$

scale controls the speed of time flow by the scale factor $f$

• 0.1 for 10 times slower than real time
• 1 as fast as real time;
• 10 for 10 times faster than real time;
• 0 or greater than 1000,000 for as fast as possible;

The corresponding application programming interfaces (APIs) are:

   public double SRTEngine::GetTimeScale();
   public void SRTEngine::SetTimeScale(double ts).
