Unfortunately we use OSISOFT - PI and Wonderware Inbatch, both are sensitive to i.e. DST changes, so keeping in synch automatically is out of the question overhere... Rgds, Dirk -----Original Message----- From: foxboro-bounce@xxxxxxxxxxxxx [mailto:foxboro-bounce@xxxxxxxxxxxxx] On Behalf Of Steinbrecher, Nick Sent: maandag 25 februari 2013 14:41 To: foxboro@xxxxxxxxxxxxx Subject: [foxboro] How to keep accurate time Dear List, We have been struggling for many years with the inability of our IA system to keep in sync with real time. We seem to lose about 1 minute per month. We are currently running IA 8.7. this gets to be frustrating when trying to correlate events outside the control system with the control system. The advice from Invensys has been that the only way to fix this is to add the GPS timekeeper function. While this is not a herculean activity it just bugs me that my home PC can keep better time than our control system. Anyone have a similar problem with other solutions?
