Why does my Vijeo Designer Alarm Log show the correct time stamp on the Magelis terminal, but shows one hour off on the Alarm Log when viewed through WebGate?

How can we help you today?

Issue
Alarm log displays incorrect time when viewing screen through WebGate

Product Line
Harmony/Magelis HMI supported by Vijeo Designer

Environment
Vijeo Designer Web Gate Feature

Resolution
If you are updating the HMI time from the real time clock on a PLC through the use of the Dialog Table feature, the hour value of the time displayed being offset by one hour is likely caused by the fact that the Dialog Table feature does not support Daylight Savings Time Automatic Adjustment.
Disabling DST on the PC used to connect to WebGate will result in the correct time stamps being displayed.
