QTime QTime::currentTime (  )  [static]

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Returns the current time as reported by the system clock.

Note that the accuracy depends on the accuracy of the underlying operating system; not all systems provide 1-millisecond accuracy.
