We have several AF Analysis that calculate the daily water flow in our system. We calculate the daily amount of flow and store it in a PI tag that resembles the base tag and add ".day" to the end of the name. The values are calculated at 2:00 am everyday and specify an offset of -2h so the value is stamped for 12:00 am. We have found that on the day when the time changes (yes we live in a state with daylight saving), the value is either written to 11:00 pm the previous day or (on the fall back day, we lose an hour) or 1:00 am on the day of the clocks spring forward. When we run reports based on these days, the value is always wrong. Is there a good way to handle the time change and get the value at the right time?
