Robust Timing Over the Internet

ChelleChelle writes "The NTP (Network Time Protocol) system for synchronizing computer clocks has been around for decades and has worked well for most general-purpose timing uses. However, new developments, such as the increasingly precise timing demands of the finance industry, are driving the need for a more precise and reliable network timing system. Julien Ridoux and Darryl Veitch from the University of Melbourne are working on such a system as part of the Radclock Project. In this article they share some of their expertise on synchronizing network clocks. The authors tackle the key challenge — taming delay variability — and provide useful guidelines for designing robust network timing algorithms."

Unsecured protocols are foolish. NTP over some secured tunneling protocol like TLS would maybe be be a solution if the server could use anything else than simple cleartext.

Ohmygod! I don't even want to think about how many problems I could have if the clock on my phone was out by 500ms...

Anal, much?
