Cause
The setting "Interval time zone" under the Trend log configuration have caused some users to believe that this setting stores trend data in either "UTC" or "Server local time"
Resolution
The trend log data is always stored in UTC time, regardless of the option selected under this setting.
This setting is intended for preventing problems with DST when the logging interval is more frequent than 1 hour.
See Interval Trend Log Properties – Basic Tab in EcoStruxure WebHelp.
