__Event class
The __Event system class is an abstract base class that serves as the parent class for all intrinsic and extrinsic events. All new event types must ultimately derive from __Event. Intrinsic events derive directly from this class. User-defined extrinsic events derive from a subclass of this class called __ExtrinsicEvent.
The following syntax is simplified from Managed Object Format (MOF) code and includes all inherited properties. Properties are listed in alphabetic order, not MOF order.
Syntax
[abstract]
class __Event : __IndicationRelated
{
uint8 SECURITY_DESCRIPTOR[];
uint64 TIME_CREATED;
};

Properties
The __Event class has these properties.
-
SECURITY_DESCRIPTOR
-
-
Data type: uint8 array
-
Access type: Read-only
Descriptor that the event provider uses to determine which users can receive the event. For more information, see WMI Security Constants.
-
-
TIME_CREATED
-
-
Data type: uint64
-
Access type: Read-only
Unique value that indicates the time the event is 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 Time (UTC) format.
For more information about using uint64 values in scripts, see Scripting in WMI.

Remarks
The __Event class is derived from __IndicationRelated, which has no properties.
