Build your Unix Epoch Converter with AI in under 5 minutes

Build a Unix epoch / timestamp converter that turns timestamps into human dates and back — seconds, milliseconds, microseconds, or nanoseconds — with the live current epoch, ISO-8601 UTC, local time, and a relative 'x ago'. Everything runs in the browser.

What is a unix epoch & timestamp converter?

A Unix epoch converter turns a timestamp — the seconds-since-1970 number you find in logs, JSON payloads, and database rows — into a human-readable date, and back again. It's a daily lookup for developers: an API returns `created_at: 1700000000`, a log line is stamped `1700000000000`, a debugger shows a raw `Date.now()`, and you need to know *when* that actually was, in UTC and in your own timezone. The canonical tools — epochconverter.com, unixtimestamp.com, the date pickers in dev consoles — all do this, but the perennial trap is the unit: classic Unix time is in seconds (about 10 digits today), while JavaScript and Java use milliseconds (13 digits), and some systems use micro- or nanoseconds. A good converter detects the unit from the value's magnitude, shows the result in UTC and local time plus a relative 'x ago', and gives you the timestamp back in every unit so you can paste whichever your system expects.

Common features

  • A live current-Unix-time readout (with a 'use now' shortcut)
  • Timestamp → date and date → timestamp
  • Auto-detect seconds / milliseconds / microseconds / nanoseconds
  • Manual unit override for edge cases
  • ISO-8601 UTC output
  • Your local-timezone time
  • A relative 'x ago / in x' readout
  • The value in every unit, each with one-click copy
  • Everything client-side — nothing uploaded
  • Light and dark themes; last input remembered

Real-world examples

Decoding an API timestamp

A developer pastes `created_at: 1700000000` from a JSON response and instantly sees it's 14 Nov 2023, 22:13 UTC — and what that is in their local time.

Telling seconds from milliseconds

Someone has a 13-digit number from a log and isn't sure of the unit; the converter auto-detects milliseconds and shows the right date instead of a year in the distant future.

Grabbing 'now' for a test

A developer needs the current epoch in milliseconds for a fixture, copies it from the live clock in one click, and pastes it into their test.

Why FloopFloop fits unix epoch & timestamp converter projects

An epoch converter is the kind of tool you reach for ten times a day, so it should be instant, ad-free, and yours. FloopFloop ships the converter you want — the units you use, your team's timezone, the formats your stack expects — on your own domain, with every conversion running in the browser. The 'timestamp console' that ships by default keeps a live clock ticking and shows the value every way at once, and the whole thing is one prompt away from being whatever fits your workflow.

Build a Unix epoch / timestamp converter. Show the live current Unix time at the top (updating every second) with a 'use now' button. Below it, one smart input that accepts a numeric epoch — auto-detecting seconds vs milliseconds vs microseconds vs nanoseconds from the magnitude, with a manual override — or a date string. From it, show the ISO-8601 UTC string, the local time, a relative 'x ago / in x', the day of the week, and the timestamp in every unit (s / ms / µs / ns) with one-click copy. Make it hydration-safe: render the deterministic ISO/unit values during SSR and gate the live clock, local time, and relative time on mount. Persist the input to localStorage. 100% client-side.

Create a tool like epochconverter.com / unixtimestamp.com: paste a Unix timestamp and see the human date in UTC and my local timezone, or paste a date and get the epoch. Auto-detect seconds vs milliseconds. Keep it fully in the browser.

Build a developer timestamp tool with a live epoch clock and a converter that handles seconds, milliseconds, and nanoseconds, shows ISO-8601, and copies any value. Add a dark console theme.

Build an epoch-to-date converter that's fast and ad-free — one box, instant results in every unit and format, and a relative-time readout so I can sanity-check a timestamp from a log.

よくある質問

What is a Unix timestamp?
It's the number of time units since 00:00:00 UTC on 1 January 1970 — the 'Unix epoch' — not counting leap seconds. Because it's a single timezone-free number, it's the standard way logs, databases, and APIs record time.
Seconds or milliseconds — how does it know?
By magnitude. A current timestamp is about 10 digits in seconds, 13 in milliseconds, 16 in microseconds, and 19 in nanoseconds, so the converter auto-detects the unit — and you can pin it manually if your value is from an unusual range.
How is this different from epochconverter.com?
Same job, but it's yours: it lives on your subdomain, runs entirely in the browser, shows the value in every unit and format at once, and you can add your team's timezone, a custom format, or a batch mode without ads. The live clock and conversions never hit a server.
Does it show my local time as well as UTC?
Yes — it shows the ISO-8601 UTC string, your browser's local time, the UTC day of the week, and a relative 'x ago / in x' so you can place a timestamp at a glance.
Is anything uploaded?
No. Every conversion runs in your browser and your last input is saved to localStorage only. The single outbound surface is the /api/health probe.
