Hello! I have made a program for a district heating plant in 2012. The freelance version is 9.2 and the customer is using Windows Xp Professional. After we get back to normal time from summer time last Saturday they get over 50 system alarms from different tags. The message from all of them is "No valid daylight saving time defined". How can i define that? The only thing I can remember that we have don is that we have adjust the system time from Control Builder.
