__ExtrinsicEvent class
The __ExtrinsicEvent system class is an abstract base class that serves as a parent class for all user-defined event types, also known as extrinsic events.
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.

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.
