Current Unix Timestamp (Live)

Need the current Unix time right now? This page shows it live and updates every second — in seconds, in milliseconds, and as ISO 8601, with both the UTC and your local representation alongside. Click any value to copy it. Everything is read straight from your device clock; nothing is fetched from a server.

How to use the Current Unix Timestamp (Live)

The two large numbers at the top are the live Unix timestamp — the first in whole seconds, the second in milliseconds. Both tick forward automatically. Click Copy under either to put the current value on your clipboard; the value is frozen at the moment you click, so you copy a clean number even though the display keeps moving.

If you want to read or screenshot a stable value, tick Freeze to pause the updates, then untick it to resume. Below the counters, the same instant is shown four more ways: ISO 8601 in UTC (the format APIs and logs prefer), a readable UTC string, your local time with its zone, and the day-of-year number.

The clock here is your computer's clock. If your timestamp looks wrong, your device time or timezone is the place to check — this tool simply reports what the browser sees.

What is a Unix timestamp?

A Unix timestamp — also called epoch time or POSIX time — is the number of seconds that have elapsed since 00:00:00 UTC on 1 January 1970, the "Unix epoch." It deliberately ignores time zones and daylight-saving rules: a given instant has exactly one Unix timestamp everywhere on Earth, which is what makes it the lingua franca for storing and comparing moments in software.

Because it is just an integer, a timestamp is trivial to store, sort, and subtract. The difference between two timestamps is a duration in seconds, with no calendar math required. Most systems use seconds, but JavaScript, Java, and many databases use milliseconds (multiply by 1000), and some high-resolution systems use microseconds or nanoseconds. The giveaway is digit count: a seconds value today has 10 digits, a milliseconds value has 13.

One historical wrinkle worth knowing: systems that store the timestamp in a signed 32-bit integer overflow on 19 January 2038, the "Year 2038 problem." Modern platforms use 64-bit integers, which push the limit hundreds of billions of years out, so for new code it is a non-issue — but it is the reason you still see 64-bit time types called out in older APIs.

Common use cases

• Seeding test data. Grab the current epoch to set created_at or expiry fields while testing an API.
• Cache busting. Append a current millisecond timestamp to a URL to defeat caching during development.
• Debugging logs. Compare a timestamp from a log line against "now" to see how long ago an event happened.
• Setting token expiry. JWT exp and iat claims are Unix seconds — copy the current value as a starting point.
