Time Synchronization in REF630

Hi,

we are using REF630 relays and I have to do the time synchronization of the relaysfor time to time updated alarming events. I already enbled the SNTP time synchronization on my OPC server (CET). Also defined the Time Synchronization in relay & defined the Ip address of the server. UTC for the site is +6 hours (= +12 half hours). when i do the OPC server management refresh, the alarm & event list got refreshed with device connection showing the server time, however for rest of the options the time is coming out to be different which means IEDs are not time synchronized.

Can any one tell me how o solve this issue.

Does i have to define my server as SNTP server aoart from defining it from CET. If yes please provide the steps.
