title: Server to ping to get exact UTC time? And Time zone information?
body: <p>I'm making a program that has a function that can only be run at a certain time. I want to make ti so people can't just change the clock time on their computer to make it work. Is there a place I can ping online that will return the exact time?</p>
  
  <p>Also, because I don't want them to be able to cheat with time zones, but I want to incorporate them, is there a way to find out the time zone a host computer is in?</p>
  
  <p>Thanks.</p>
