Change Source Timestamp

[vic-951]

Hello there,

I have a problem with the source timestamp, I use OPC-UA server for historical data for another energysoftware. My problem is that I get every few minutes cached data with the original timestamp. But everything I tried didn´t changed my sourceTimestamp on the opc-ua server.

Here is my flow, how I try to add values with timestamp, my timestamp is set in msg.timestamp. I also tried msg.sourcetimestamp, how can I change it?
