title: Is there a preferred way to get the system time in cocos2d-x?
body: <p>I am writing a cross-platform application in Cocos2d-x.  I need to get the time to create a countdown clock to a certain time of day.  Since it is in C++, I can use time(...), mktime(...), and difftime(...) if I need to as a direct approach.</p>
  
  <p>Is there a preferred method in Cocos2d-x for doing this in a cross-platform way (i.e. something built directly into the framework)?  I want the app to work the same on iPhones, iPads, and Android.</p>
