Simple real time clock based on Ogre::Timer.
The class can be used to both capture the current real time or to incrementally capture the time and then distribute that time information via Clock& references (for instance for the game tick).
Precision:
- Precision
- The maximum precision is given by the Ogre::Timer and that is somewhere in the microsecond range for both Windows and UNIX.
- Remarks for Usage on Windows
- For proper functionality this class MUST be used in the same thread!
Furthermore it might be possible that the Ogre::Timer has a performance caveat because it will only capture the time on the same CPU core. Confining the main thread to one process could speed up the game.
