Discrepancy in lastActive Value from Trello SCIM Users API

We are using the Trello SCIM Users API to retrieve a list of Trello users along with their lastActive timestamps. However, during testing, we noticed that the lastActive value returned by the API does not match the actual last activity of the users in Trello.

Has anyone else encountered this issue? Are there known limitations or workarounds to get an accurate last activity timestamp? Any insights or guidance would be greatly appreciated.
