You have to decide who is the time master in your system and then let the time master synchronize all the other nodes. You also then need to set the time at the time master only. The orther nodes will be synchronized by the time master.
It seems to me that in your system the AC 800F is the time master, but it seems not connected to a radio clock / GPS clock. So over time its system time will deviate from the correct time.
It seems also, that the OPC Gateway running on your PGP PC is set to get synchronized by the controller, which is fine. The OPC GWY will synchronize the PC time once it receives time synch messages from the Controller. Setting the PC time manually will not help, because the PC is not the time master. The next time-synch message from the controller will set the PC time back to the controllers time (which is off 13 minutes as you say).
You need to set the controller time via Freelance engineering in commissioning mode. Menu Options/Set System Time ...
If you do not want to set the controller time now and then you need to connect a GPS clock to the controller.
Another possibility is to let the PC be the time master. Then the OPC GWY will synchronize the AC 800F to the PC time. You need to do some reconfiguration in the Settings (Freelance Settings program) on the PGP PC and configure the OPC GWY to synchronize the controller.
