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?

If you are updating the HMI time from the real time clock on a PLC through the dialog table, it may be caused by the fact that the dialog table does not currently support Daylight Savings Time Automatic Adjustment. If you disable DST on the PC used to connect to WebGate, you will see the correct time stamps.
