   Difference between clock_t and time_t
  I'm wondering what is the difference between to the two I understand that time_t is based off time but clock_t is based off clock ticks??? I just need some clarification.   
  The documentation says that clock returns number of clock ticks elapsed since the program was launched.Whereas time is the current calendar time in milliseconds since midnight, iirc.Note that both types are just integers, but typedef'd to clarify their usage.
