jmUnfortunately for us, the traditional and most widespread method for clock synchronisation (NTP) has been caught up in a DDoS issue which has recently caused some ISPs to start blocking all NTP communication. [....] Because the DDoS attacks are so widespread, and the lack of obvious commercial pressure to fix the issue, it’s possible that the days of using NTP as a mechanism for setting clocks may well be numbered. Luckily for us there is a small but growing project that replaces it.
tlsdate was started by Jacob Appelbaum of the Tor project in 2012, making use of the SSL handshake in order to extract time from a remote server, and its usage is on the rise. [....] Since we started encountering these problems, we’ve incorporated tlsdate into an over-the-air update, and have successfully started using this in situations where NTP is blocked.
