## Time, timestamps, and time zones in one place

The [Time Converter](https://www.jpkc.com/tools/time/) converts between **Unix timestamps** and readable date/time values, shows the **current time** live in many formats, and calculates **time differences** between two points in time. No mental arithmetic, no library to install — you enter a value, click **Convert** or **Calculate**, and get the result instantly.

At its core the tool answers three recurring questions from everyday development and admin work: *Which date hides behind this Unix timestamp?* *Which timestamp belongs to this date?* And: *How much time lies between these two points?* On top of that comes a **live clock** you can display in any time zone and language format.

The Time Converter is built for anyone who handles timestamps regularly: **developers** who hit bare Unix seconds in logs, databases, or API responses; **admins** tracing cron runs or token expiry times; and anyone who quickly needs to know how a moment looks in another time zone or language.

## What the Time Converter does — at a glance

- **Current** — a **live clock** that refreshes every second and shows the current time in eleven formats at once (Unix timestamp, ISO 8601, localized long and short forms). Can be paused and resumed with a button.
- **Convert** — converts **date/time → Unix timestamp** and **Unix timestamp → date/time**, each into the same eleven formats. A **Get Server Time** button fetches the current timestamp straight from the server clock.
- **Timeago** — calculates the **difference** between a date and *now*, or between two freely chosen points, broken down by years, months, days, hours, minutes, and seconds plus a readable summary.
- **Language Format** — render the output in over 60 language formats (German, English, French, Japanese …).
- **Timezone** — display the output in a chosen time zone (CET by default, plus generic zones and `Etc/GMT` offsets).

## The tech under the hood

All the time logic runs through the JavaScript library **Day.js** with its plugins for UTC, time zones, localized formats, relative time, and parsing custom formats. **Unix timestamps are always handled in seconds** (not milliseconds) — the way PHP's `time()` or Unix logs deliver them.

The time-zone picker is a **curated list** of generic zone abbreviations (CET, EET, EST, PST8PDT …) and `Etc/GMT` offsets — not the full IANA city catalog and not your browser's automatic time zone. Exactly which zones are on offer and what to watch for with the `Etc/GMT` signs is covered in the **manual**.

## Architecture: client-side — with an honest server clock

Conversion, comparison, and formatting happen entirely **inside your browser**; the values you enter never leave it. There is exactly **one** optional server interaction: the **Get Server Time** button queries a small endpoint (`/tools/time/time/`) that returns nothing but the server clock's current Unix timestamp as plain text. Nothing of yours is transmitted — the response is just a number. If you type values yourself, no server contact happens at all.
