1 使用QDateTime類(毫秒精度)函數
QDateTime current_date_time = QDateTime::currentDateTime(); QString current_date = current_date_time.toString("yyyy-MM-dd hh:mm::ss.zzz");
2 使用QTime類spa
QTime current_time = QTime::currentTime(); int hour = current_time.hour(); //當前的小時 int minute = current_time.minute(); //當前的分 int second = current_time.second(); //當前的秒 int msec = current_time.msec(); //當前的毫秒
3 使用GetLocalTime函數(毫秒精度)3d
SYSTEMTIME sys; GetLocalTime(&sys); printf("%4d/%2d/%2d %2d:%2d:%2d.%3d\n",sys.wYear, sys.wMonth, sys.wDay, sys.wHour, sys.wMinute, sys.wSecond, sys.wMilliseconds);
