title: Network Time Protocol for iPhone
body: <p>I am writing an application that requires accurate timing. After asking <a href="https://stackoverflow.com/questions/2264197/how-to-accurately-sync-time-between-iphones">this question</a>, I have decided to investigate using NTP or maybe Simple NTP.</p>
  
  <p>Is there any open source implementation of these protocols for the iPhone? So far I have managed to find a <a href="http://www.tuaw.com/2008/01/23/tuaw-responds-ntp-for-the-iphone/" rel="nofollow noreferrer">broken link</a>. I am also aware that NTP has a <a href="http://www.ntp.org/downloads.html" rel="nofollow noreferrer">C reference implementation</a>, so I am trying to see how much effort it would require to make it work on the iPhone.</p>
  
  <p>Update: I thought I had a working link, but it is to the Wayback Machine, which only saves text, not files <a href="http://web.archive.org/web/20080401170640/http://wickedpsyched.com/iphone/ntp" rel="nofollow noreferrer">link that works</a>.</p>
