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.

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? -george On Mon, Nov 19, 2012 at 6:08 PM, Wallace Keith <kwallace () pcconnection com> wrote:Just got paged with a pbx alarm that had 1970 as the year.
