About Unix timestamps

A Unix timestamp counts seconds (or milliseconds) since 1970-01-01T00:00:00Z and represents a single instant — it has no timezone of its own. UTC and Local above are two different readings of that same instant; "Local" uses your browser's timezone. Auto-detects seconds vs. milliseconds by digit count (10 digits or fewer is seconds, 11+ is milliseconds) — switch to a manual unit if that guess is wrong. Converting a local date/time on a daylight-saving-time transition day can hit a wall-clock time that never happened or happened twice; this tool reports that rather than guessing.
