Timestamp Converter
Convert between Unix timestamps and human dates, timezone aware. No uploads.
How does the timestamp converter work?
The top card shows the current Unix time in both seconds and milliseconds,
ticking live. Paste any Unix value into the second card and Lime Kit
auto-detects whether it's seconds or milliseconds before formatting it as a
human-readable date in both your local timezone and UTC, using the
browser's Intl.DateTimeFormat.
Need to go the other way? Pick a date and time in the third card and get back its Unix timestamp in both seconds and milliseconds. Everything runs locally — nothing is sent to a server.
