I am struggling to find the initial timestamp of a point's current value. As seen in the plot, the tag has had the value of "1" for several days. Is there a simple way to find out exactly when the value of the point changed from "0" to "1"? I have tried using PrevVal and PrevEvent but those do not provide the answer; since the compression max time has elapsed the previous value is "1" as well. Thank you for the help!
