When there is a significant difference between the user's browser's time and the system time, a button appears in the web UI to fix the system time. This time will then be used to correct both data inside of PCAPs and any metadata. We don't actually set the system time to this value. Instead, rayhunter adjusts any timestamps it handles by an offset. That offset defaults to zero, and the user adjusts it by hitting the button in the web UI. The main reason for this is device portability. I haven't investigated whether it would actually be easy to set the real system time. It's possible that it works the same way across all devices.
Rayhunter
Rayhunter is a project for detecting IMSI catchers, also known as cell-site simulators or stingrays. It was first designed to run on a cheap mobile hotspot called the Orbic RC400L, but thanks to community efforts, it can support some other devices as well. It's also designed to be as easy to install and use as possible, regardless of your level of technical skills, and to minimize false positives.
