Unix Timestamp Converter
Private by design — runs entirely in your browser
Convert between Unix timestamps, ISO 8601 strings, and human-readable dates in your browser. Toova handles seconds, milliseconds, and nanoseconds, supports every timezone, and runs entirely on your device — perfect for debugging logs, API responses, and database fields.
Seconds, milliseconds, and beyond
Unix timestamps come in three common flavors: seconds (most systems and Unix tools), milliseconds (JavaScript's Date.now), and nanoseconds (some high-precision logging systems). Toova auto-detects the unit based on the magnitude, but you can override it when ambiguous. ISO 8601 strings, RFC 2822, and many other formats are accepted on input — paste anything time-like and Toova does its best to interpret it correctly.
Timezone control
Display the result in any IANA timezone, not just UTC. That makes Toova essential when correlating logs from servers in different regions or debugging an event that fired "at 3 PM" without specifying the zone. Switch between timezones to see how the same moment appears in each, with daylight saving handled automatically based on the date.
Local-only conversion
Conversions happen entirely in your browser. The timestamps you paste — often the only clue tying a log entry to a customer interaction — never leave the page. That matters when the surrounding context could leak information about your users. The Network tab will stay empty during conversion, and the page works offline after first load.
Frequently Asked Questions
- Is my timestamp in seconds or milliseconds?
- Roughly: a 10-digit number is seconds, a 13-digit number is milliseconds. Toova auto-detects based on the magnitude, but you can override the unit when the input is ambiguous.
- What timezone is the result in?
- Toova displays in your browser's local timezone by default. Switch the timezone dropdown to view the same moment in UTC or any other IANA zone — useful when correlating logs from servers in different regions.
- Why does the result differ from my expectation?
- Usually a timezone mismatch — the timestamp is in UTC but you are reading it as local, or vice versa. Toova always shows both UTC and your selected timezone side by side so the conversion is obvious.
- Can I convert a date string back to a timestamp?
- Yes. Paste an ISO 8601 string, RFC 2822 date, or any common date format and Toova returns the corresponding Unix timestamp in seconds and milliseconds.
- Is my data sent anywhere?
- No. Conversion happens entirely in your browser.
