CUCM 8.6 Time is't stable.Urgent

[waqas sardar]

We are using NTP server for time synchronizing.Time is not stable in this sense hat it strat increasing from Monday to Satuday by 10sec and reset  again on Moday.

Previously we were using CUCM.now we upgade it to 8.6 version,but problem is still as it is.Please suggest some solution.

Are you using a valid NTPv4 server running on IOS or Linux? Is it syncronized to a reliable Stratum 1 or 2 server? Windows does not provide valid NTP time as it uses a stripped down SNTP protocol. Essentially, this is not a CUCM problem; figure out why the time is drifting on the NTP server.
