    Easy way to insert PI Data at the current server time using the SOAP interface


      Hi there,


      I'm using Python to communicate with the PI SOAP Web Services (we don't have the REST-web api available yet unfortunately), which works fine for now.

      I am however, running into minor problems writing data to PI tags due to time synchronization differences between servers.


      Is there a convenient way to write data to a PI tag at the current server time? Providing the SOAP function with "*" as date does not work.


      Below is the code I currently use:


      def insert_value(self, tag, value, time=datetime.datetime.now()):
            aos = self.client.factory.create("ArrayOfTimeSeries");
            timeseries = self.client.factory.create("TimeSeries");
            aof = self.client.factory.create("ArrayOfTimedValue");
            timedvalue = self.client.factory.create("TimedValue");
            timedvalue.value = value
            timedvalue._Time = time
            aof.TimedValue = [timedvalue]
            timeseries.TimedValues = aof
            timeseries._Path = tag
            aos.TimeSeries = [timeseries]
            # write to server
