WinCC Unified Systems: Alternative Duration between Touch Display & Alert viewer

Hi colleagues, I'm using a MTP1000 Unified Comfort V18.0.0.1.
The panel takes the time from the PLC (NTP Server)(UTC 0). But in the alarm viewer, the alarms appears with a different hour (UTC +1).
I would like that the alarms in the alarm viewer take the same time of the panel.
Thank you.

Alarm Time Discrepancy in MTP1000 Unified Comfort Panel

You are experiencing a time difference between the panel display (synchronized with the PLC/NTP server - UTC 0) and the alarm viewer (showing UTC +1). This is often due to the panel's internal time zone setting.

Solution: Verify and adjust the time zone setting within the HMI panel configuration. Ensure it's correctly set to UTC 0 to match the PLC's time.

Steps:

  1. Open your WinCC Unified project.
  2. Navigate to 'Project Settings' -> 'System Settings' -> 'Time Synchronization'.
  3. Confirm the 'Time Zone' is set to '(UTC) Coordinated Universal Time'.
  4. Download the changes to the HMI panel.

Further Support: Refer to the Siemens Support article for detailed guidance: Time synchronization in WinCC Unified V18. You can also find relevant information in the WinCC Unified documentation within SiePortal.
