QT如何获取当前时间

Qt 中有函数获取当前系系时间么。
我想取得系统当前时间，精确到毫秒，要怎么实现？

Answer 1

QTime QTime::currentTime () [static]

This is an overloaded member function, provided for convenience.
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.
----------------------------------------------------------------------------------------------------------------
int QTime::msec () const
Returns the millisecond part (0 to 999) of the time.
See also hour(), minute(), and second().
