## Description

CCTV Clock Synchronizer is an essential tool for investigators and detectives working with CCTV footage that has inaccurate timestamps. CCTV DVR clocks often deviate from real time by days, months, or even years due to clock errors and intercalation differences, making it difficult to determine the exact timing of recorded events.

This Chrome extension allows users to input the known CCTV clock time and the approximate real time, then calculates the corrected real time, taking into account complex time discrepancies including multi-year differences and calendar intercalation. It simplifies the process of synchronizing two different clocks, saving time and reducing uncertainty in forensic investigations involving CCTV footage.
