FAQ
How to tell seconds from milliseconds?
The tool auto-detects by magnitude: ≥1e12 is treated as ms, otherwise seconds (current second-level timestamp ≈1.7e9).
UTC vs local time zone?
UTC is the global uniform time; local time zone shows per your region. The underlying moment is the same, only the display changes.
