Different time zone in AC800M 1oo2 Connectivity servers
We are trying to configure the actual time zones in xA5.0 with Ac800M connect with redundant domain controller.
Here controller as acts as timemaster and CS as afw time server.
We are planning to change the timezone (GMT+5.3->GMT+4) for all the system nodes and controller
the plan we made is changing time zones in domain controller first and then standby afw time server (CS) then master CS and other nodes and at last controller time zone.
doubt:while changing the time zone in the master CS other standby CS has diff time zone shall at this point of time alarm/event representations will capture which time zone?
Timezone is like a "skin", below the surface all exchange is made in UTC format.
I haven't verified, but if you begin in the controller (change offset, then system's UTC time to restore "correct time") there may be no skewed alarms or events at all.
But if AE is timestamped in OPC server, there may be skewed alarms or events until you have corrected the offset in the connectivity server.
The server with Event Collector in "Service" state is the active one.
