This error will cause data graps in your trend. The most likely reason you are seeing this issue is that a time sync is running and changing the historian clock time. This is especially true if you are running your Historian on Hyper-V or VMware. The way to fix this error is to not change the Historian time. Have all you clients sync their time to the Historian using net time. The attach technote explains how to setup net time.
