Can anyone let me know, how do we get the Last Updated time of a particular CONS

My Use Case is to display the initial value of a constant in a text field with the Last Updated Time. If the User updates the value, then I'll update the constant with the Update Constant smart service. So, how do I retrieve the last updated/modified time of a constant??
