Organization Export - Users - Last Session Creation Time


We’re trying to set up some reporting on our Asana usage and one of the metrics we’re interested in is the last time a user had activity in Asana.

When we get the JSON objects through the Org Export end point, the field last_session_creation_time in the User type is int64, unlike all the other time stamps that are string.

What does this value represent and how do I parse it?
