How to write current time not UTC time to OPC UA tag?

01 Oct 2018 18:43 #6727 by support
Standard OPC UA data type for time data is UtcTime. It is always in UTC, and has not time zone information it.

Assuming that the variable you are writing is of this data type, there is no way you could store the time zone information into it. If you want to properly write your current time to it, you should use DateTime.UtcNow.

I would like to write current timezone (Pacific) to OPC UA tag defined as below.


I use the code below to write to the Timestamp node. However, When I used either DateTime.Now or DateTime.UtcNow, it always wrote UTC time not the current time zone value. Please advise. Thanks

new UAWriteValueArguments(strOPCServer,
strAddress + "Timestamp", DateTime.Now)
