I have defined an AF Attribute of the type string that is not connected to a datasource. I'm able to write a value (including timestamp) to the attribute, but when I look at the PI Explorer or I read the data of the attribute the timestamp contains 1/1/1970 12:00 AM instead of timestamp that was specified. Is this normal behaviour or do I something wrong?
Below you can find the code that I used to write a value to AF.
OSIsoft.AF.Asset.AFValue val = new OSIsoft.AF.Asset.AFValue(); val.Value = value; val.Timestamp = new OSIsoft.AF.Time.AFTime(DateTime.Now); val.IsGood = true; attribute.SetValue(val);
