FAQ

Is my timestamp in seconds or milliseconds?
If it has 10 digits it's usually seconds; 13 digits is usually milliseconds. When unsure, toggle s/ms and see which yields a realistic date.
Why is the time different from my system log?
Logs may be in UTC while your device shows local time. This page shows both UTC and local formats.
