title: How can I be informed when Windows update its system time?
body: <p>case: I dont allow my Windows PC to connect to internet. My PC uses internal clock. After a while, I connect my Windows PC into the network, and it receives time packages from internet and update its system time. Now, how can I get informed when my Windows Operating system received a time package and update its own system time from internet. I want to write an application which:
  1- get informed about this receiveing time package (NTP) &amp; time update, 
  2- make own LOG (not very important how? just a printf is enough), like: "System Tiems is updated from 12.38 to 12:44".</p>
  
  <p>Thank you guys for your info &amp; help.
  Regards,
  Wolfgang</p>
