The Global Clock
================

The global clock is an instance of the
`ClockObject <http://www.panda3d.org/reference/python/class!panda3d.core.ClockObject>`__
class. 

.. only:: python

    It gets imported into the global namespace when you load the
    DirectStart/Showbase modules.



.. only:: cxx

    There's a single instance of it already initialized that you can access
    statically.


To get the time (in seconds) since the last frame was drawn:


.. only:: python

    
    
    .. code-block:: python
        
        dt = globalClock.getDt()
    
    




.. only:: cxx

    
    
    .. code-block:: cpp
        
        double dt = ClockObject::get_global_clock()->get_dt();
    
    


Another useful function is the frame time (in seconds, since the program
started): 

.. only:: python

    
    
    .. code-block:: python
        
        frameTime = globalClock.getFrameTime()
    
    




.. only:: cxx

    
    
    .. code-block:: cpp
        
        double frame_time = ClockObject::get_global_clock()->get_frame_time();
