hosted Posted October 2, 2008 Report Share Posted October 2, 2008 I am having a few CS410's that are loosing their time. Box this morning has an uptime of 17 hours. however I ssh'd and ran 'date' and it says: Tue Jan 1 03:13:45 UTC 2008 Which means 3 hours ago, the date reset for no reason. any ideas?

Sounds like a problem with DNS or NTP itself. Is the PBX able to resolve pool.ntp.org? Quote Link to comment Share on other sites More sharing options...
hosted Posted October 3, 2008 Author Report Share Posted October 3, 2008 yes. so are you saying that if the ntp server which checks the time every so often doesnt get a reponse the time on the PBX will reset to JAN 1? 00:00 ?? because it was working before hand.

On the CS410, the PBX first uses ntpclient to set the initial time on the Linux level. Then the time is not set any more on the OS level. The PBX uses NTP just to keep track of time drifts, but does not change the time on the OS any more. When you change the NTP server from the web interface, you need to reboot the system before that takes effect. Quote Link to comment Share on other sites More sharing options...
hosted Posted October 7, 2008 Author Report Share Posted October 7, 2008 ok but the box never rebooted and the customer called me and said their night service was active. I looked at the web interface and the date/time was wrong. so I sshed to the box and it was reset to Jan 1 at 3:00 AM. (which i assume means 3 hours ago the date reset. the pbx was not reset. so my question is why did the box date reset? doesn't make sense. I have 1 chronic box that doesn't this and 2 others so far that might have just been a fluke. Quote Link to comment Share on other sites More sharing options...

The PBX actually does it's own NTP and calculates the drift from the OS. Changing the time on the OS screws up the callbacks. When you have a phone call and set the time on the OS, there will be a major RTP hickup. That's why we accept that the clock drifts and calculate the "real" time with this trick.

mattlandis Posted November 18, 2009 Report Share Posted November 18, 2009 Hello, I had exactly the same problem and it was caused by a bad IP setup on the cs410. Bad gatway ip address. thanx Matt Quote Link to comment Share on other sites More sharing options...
hosted Posted November 19, 2009 Author Report Share Posted November 19, 2009 I only had this problem with the white box, but the black box has been just fine for NTP. just make sure your runing 3.4 and the latest MSP software... If you have a white box, I just installed my own ntp client Quote Link to comment Share on other sites More sharing options...
