Anyone check out the NIST GPS Archive? http://www.nist.gov/pml/div688/grp40/gpsarchive.cfm -Mike On Mon, Nov 19, 2012 at 7:58 PM, Sid Rao <srao@ctigroup.com> wrote:
We had multiple servers synchronized with Windows/MS time change their clock to the year 2000 today. It broke many things, including AD authentication.
These servers had been properly synchronized for years.
They were synchronized with Microsoft and NIST NTP servers.
This may not be isolated.

crossreplying to outages list.
Is anyone ELSE seeing GPS issues? This could well have been an unrelated issue on that particular PBX.
If this was real, then the mother of all infrastructure attacks might be underway...
One glitch on tick and tock and one malfunctioning PBX is not sufficient evidence of pattern - much less hostile activity - to induce panic, but it would perhaps be a wise time to check time-related logs?

Just got paged with a pbx alarm that had 1970 as the year. By the time I logged in , it was showing 2012. Using GPS for time and date.

Hello,
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
Thanks, Van
NTP should be immune from this sort of behaviour unless you did a ntpdate at the wrong moment. The clocks should have been marked as insane.
