Issue

The Event Notification Module (ENM) Monitoring and Diagnostics pages display [Invalid Date] in timestamp columns instead of the actual timestamp.

Product Line

ENM 8.3.x

Environment

PowerSCADA Expert 8.1

Power Monitoring Expert 8.1

Cause

Some Windows locales use special characters for AM/PM notation (e.g., Italian [Switzerland], Chinese [Singapore]). When Windows is configured to use one of these locales, ENM cannot properly format timestamps, resulting in [Invalid Date].

Resolution

Change the Windows locale to one that uses standard AM/PM characters.
Examples:

• Italian (Italy)
• Chinese (China)

Steps:

1. Open Control Panel → Region and Language.
2. Change the locale to a supported setting.
3. Restart ENM services if necessary.

Notes

• This issue applies only to ENM 8.x and PME 8.1.
• Newer versions of PME and ENM have resolved this locale parsing issue.
