  uint64 TIME_CREATED;
};

Properties

The __SystemEvent class has these properties.

SECURITY_DESCRIPTOR

Data type: uint8 array

Access type: Read-only

Descriptor used by the event provider to determine which users can receive the event. This property is inherited from __Event.

Note

A NULL Access Control List (ACL) in the SECURITY_DESCRIPTOR grants unlimited access to everyone all the time. For more information, see Creating a Security Descriptor for a New Object.

TIME_CREATED

Data type: uint64

Access type: Read-only

Unique value that indicates the time at which the event was generated. This is a 64-bit value that represents the number of 100-nanosecond intervals after January 1, 1601. The information is in the Coordinated Universal Times (UTC) format. This property is inherited from __Event.

For more information about using uint64 values in scripts, see Scripting in WMI.

Remarks

The __SystemEvent class is derived from the __ExtrinsicEvent class.
