Problem

The QA team is profiling performance regressions and wants to know which device and operating system each unusually long session ran on. For every session that lasted more than a thousand seconds, return the user, the device type, the operating system, and how long the session lasted.

Summary

When a session drags on, the platform it ran on is the first suspect.
