There is a property(PYLASTSIGNON) that captures the login time of Operators, I need a similar property which will capture the logout time of users(need to show in a report), please provide suggestions on how to achieve this.
As Shubham mentioned, there is no OOT property which holds the logout time. Alternatively, you can try creating a DateTime property in 'Data-Admin-Operator-ID' class. Try populating the value to the property on calling the logout or timeout activity. Also you might need to consider scenarios like passivation.
