Detailed Description

A clock for measuring event times in ms.

Usage: Call measure() before and after the event being timed. Call difference functions diff_s() or diff().

Example

  aclock ac;
  
  ac.measure();
  event();
  ac.measure();
  cout << "The event took " << ac.diff_ms() << "ms" << endl;
