Question

我试图计算从我的设备发送数据到azure服务总线主题之间的时间。我有天蓝色的功能来听主题。此外，我发送到主题的数据有一个DateTime。在azure函数中，我创建新的DateTime并从主题数据中减去DateTime。它应该给我发送到接收之间的时间。但是，我得到了很多负面数据。

    try
    {
        await client.PostAsJsonAsync("api/device", device);
        releaseLoop= true;

    }
    catch (Exception e)
    {
        log.Info("Exception Message: "+e);
    }

    finally
    {
        log.Info($"{data.DeviceName} Total runing time "+(DateTime.UtcNow-data.timerInfo).Milliseconds+"ms");
    }



logInfo from azure function.
