Private by design. Your input never leaves this browser. Conversions run locally on your device.
What this tool handles
- Seconds, milliseconds and microseconds are told apart by digit count, or can be forced.
- Shows ISO 8601, UTC, a chosen time zone, and how long ago the instant is.
- 10 digits is seconds, 13 is milliseconds, 16 is microseconds.
- Converts in both directions: a timestamp to a date, or a date back to a timestamp.
