StampLens — timestamp converter

Select any timestamp or date on a page and see it in your time zone: Unix s/ms/µs/ns, ISO 8601, RFC 2822, log formats.

StampLens turns any timestamp on any page into a time you can read — in your time zone. Select a Unix timestamp, an ISO date or a log line, and a small card appears next to it: • the time in your default time zone, with the date and how long ago it was • the same moment in UTC and any other zones you add • every format, one click to copy: Unix seconds, milliseconds, microseconds, nanoseconds, ISO 8601 (UTC and local), RFC 2822, SQL It reads what logs and APIs actually write: • Unix timestamps in s, ms, µs and ns — chosen by length, switchable in one click (19-digit nanoseconds stay exact) • ISO 8601 / RFC 3339, RFC 2822 and HTTP dates, JavaScript Date strings, Unix `date` output • timestamps inside log lines — web server, system and application logs • MM/DD vs DD/MM — both readings offered when a date is ambiguous • Chinese dates such as 2024年11月5日 下午4点 • MongoDB ObjectIds, UUID v1/v7 and ULIDs (their creation time) No time zone in the text? StampLens says so, reads it in your default zone, and lets you switch with one click. Also included: • A toolbar converter: the current Unix time, and a box to paste anything into • Right-click → Convert, and a keyboard shortcut (Alt+Shift+E, ⌥⇧E on Mac) • Choose how the card appears: right away, a small button first, or only while Alt/Option is held • Light and dark appearance • Optional Keepware account: sign in with Google to use the same settings in every browser Private by design: StampLens looks only at the text you select, checks it on your computer and never sends it anywhere.
