timezone in ntp status

Hi

Please find below the output of "show ntp status" command on a NTP Server & client Routers.

NTP Server

Clock is synchronized, stratum 2, reference is 208.184.49.9

nominal freq is 250.0000 Hz, actual freq is 250.0001 Hz, precision is 2**18

reference time is C6D04612.22EA36B7 (21:23:14.136 kuwait Mon Sep 12 2005)

clock offset is 0.4224 msec, root delay is 217.96 msec

root dispersion is 1.24 msec, peer dispersion is 0.82 msec

NTP Client

Clock is synchronized, stratum 3, reference is xxx.xxx.xxx.xxx (IP address of the NTP Server)

nominal freq is 250.0000 Hz, actual freq is 250.0055 Hz, precision is 2**24

reference time is C6D04AF3.9FC434D0 (18:44:03.624 UTC Mon Sep 12 2005)

clock offset is 0.1061 msec, root delay is 220.26 msec

root dispersion is 1.07 msec, peer dispersion is 0.03 msec

The NTP Server's clock timezone (Kuwait) is configured properly. Why the NTP Client router (Shows UTC timezone) doesn't have the same timezone as of the NTP Server?

Also the following messages keep appearing on the console of the NTP Server Router. Is it related to NTP?

Appreciate your reply.

Thanks in advance. // Anup

I believe the console message you ask about is not at all related to your NTP question. It looks to me like something is unstable about clocking for some serial interface or controller.

The explanation of your NTP question is that NTP transmits time in Universal Time (UTC) and the router translates that time into local timezone if it is configured to do so. Apparently the server has been configured to adjust for local time of Kuwait and the client has not. The command to adjust for local timezone is in global config:

clock timezone

If you configure this on the client you should find that the time is correctly translated.

Also, if you are in a place where you have Daylight savings, specify the daylight savings settings using clock summertime command.h
