DateTime.Now.ToShortTimeString神秘地增加了一个小时:S

所以我用这样的东西

   XmlAttribute receivedDateTime = SettingsFile.CreateAttribute("ReceivedDateTime");
receivedDateTime.Value = DateTime.Now.ToShortDateString() + " " + DateTime.Now.ToShortTimeString();  

  Debug.WriteLine("Adding Date Time in addMessage method : " + DateTime.Now.ToShortDateString() + " " + DateTime.Now.ToShortTimeString());
  Debug.WriteLine("Short Time Only: " + DateTime.Now.ToShortTimeString());
  Debug.WriteLine("Long Time Only: " + DateTime.Now.ToLongTimeString());
  Debug.WriteLine("Local Time: " + DateTime.Now.ToLocalTime());

所以如果实际时间是 10.15 AM

Adding Date Time in addMessage method : 8/3/10 11:15 AM
Short Time Only: 11:15 AM
Long Time Only: 11:15:51 AM
Local Time: 8/3/10 11:15:51 AM

我知道这一定是个很小的错误。。。因此,如果有人能指出这一点,我们将不胜感激。它是否与GMT或UTC或任何文化有关?
