Which time zone Vijeo Designer uses for Data Logging?

Published date: 30 October 2019

Targets store data using Greenwich Mean Time (GMT) and display data using the target's Time Zone and Daylight Saving Time settings. Therefore, the time displayed when viewing data at run time is GMT time, plus the Time Zone, plus Daylight Saving Time. When the time changes due to Daylight Saving Time, the stored data will not change, but the time displayed will. This applies to logged data, alarms, and event logs.
The normal behaviour for the Trend Graph and the Alarm Summary objects is that the data are displayed by using GMT + Time Zone + DST.
