Problem

Scenario

You're working with raw telemetry exports and need to prepare them for downstream analysis. The file is large, timestamps are inconsistent across sensors, and some records are malformed or duplicated.

Question

Given a massive, messy log file of sensor readings with mismatched timestamps, how do you align and clean the data in Python?
