I'd love if one of their admins could explain what happened, for educational benefit at bare minimum. -- | Jeremy Chadwick jdc@koitsu.org | | UNIX Systems Administrator http://jdc.koitsu.org/ | | Mountain View, CA, US | | Making life hard for others since 1977.

Scott, I can confirm this had happened on one of my test servers - it was pointing to tick.usno.navy.mil and tock.usno.navy.mil at the time.

Did anyone else experience issues with NTP today? We had our server times update to the year 2000 at around 3:30 MT, then revert back to 2012. -----------------------------------------
You need to provide more information. For example, what NTP source are you using?
