I am trying to set a new value to a point's attribute of Timestemp type, but I seem to set the value uncorrectly since the value is set to 0. More specifically, I am trying to set "creationdate" attribute value by using PIPoint.SetAttribute("creationdate", new AFTime(new DateTime( 2018,7,19,2,4,0)), but the attribute value is not set. It is set to zero instead. What Am I doing wrong?
You cannot set the creation date attribute because that point attribute is set by the PI Data Historian at the time the point is initially created.
Hi Dan,
I set the "creationdate" attribute as an example, what about other
timestemp type attributes? How can I set them?

Or is it true for all timestemp attributes, and non of them are
modifiable?

As Dan Fishman stated, these particular point attributes are system-assigned and cannot be changed. See this link for more.
For the larger topic of any and all point attributes, see this link.
