官网提供了例程，官网真是个宝库。基本ADS的操作都里面有例程了，但是可能会稍微分散一点，不过多看几遍，也就慢慢整理你所需要的东西出来了。

25 GetTimeZoneInformation(&TimeZoneInformation);
26 SystemTimeToTzSpecificLocalTime(&TimeZoneInformation, &SystemTime, &LocalTime);

28 // Print out the timestamp
29 qDebug() << LocalTime.wHour << ":"
30 << LocalTime.wMinute << ":"
31 << LocalTime.wSecond << '.'
32 << LocalTime.wMilliseconds;

34 //这样子不行，貌似Qt不支持这种timeStamp
35 //qDebug() << QDateTime::fromTime_t(pNotification->nTimeStamp);
