    Action operation sending previous value instead of current value

    Hi,
    this is my first post here, as always i manged to find what i need,
    we are using zabbix for few years now and we love it, mostly we are using zabbix to monitor SNMP devices , recently we want to monitor windows eventlog for application error,
    all the setup is been done, item,trigger, action all added and test phase was complete success ,
    for test phase we installed windows agent on few PCs in another office that is connected to our equipment center via VPN,
    but when we installed the windows agent on PCs that are located in same LAN with Zabbix server when trigger is fired we are receiving notification with previous value of item(in our case previous application error event) at same time notification belong to other PCs that are connect over internet is correct(exact last event has been sent), i tried many thing but couldn't solve this,
    only thing that i found is that in action operation if i set 2nd step to send notification(email,sms,...) and have the step duration 60s then it will send the current value,but this 60s is high for our project as we need to received the notification instantly or atlease 10-20seconds later but minimum is 60s by default,
    i would appreciate your help in this matter if someone encountered this issue , or put me in the right direction .

      Please check if system time on those agent hosts are correct. It is advised that all machines are updating the system time using NTP. For the hosts that are not connected to the internet you can set up internal NTP server.

        thanks for pointing this out , true, those host are on different timezone, and we cannot put it on same timezone as zabbix server, because those host are video playout servers that timezone is set by TV channel targeted region ,
        is there anyway to offset the timezone difference in zabbix windows agent or zabbix server for hosts that are on different timezone?

          Your issue is not a timezone but out of sync system time on those machines.

            thanks Dimir, yes those host didn't had internet time synchronization enabled ,as internet access was block on those, everything is working normal as soon as i added local NTP to those host
