How to Use Timestamp Converter

Converting Unix timestamps to dates (and vice versa) usually means using a script or a calculator. The Timestamp Converter does it in the browser: enter a timestamp or pick a date and get the human-readable result or epoch value—no sign-up and no data sent to a server.

What is a Unix timestamp?

A Unix timestamp is the number of seconds that have elapsed since January 1, 1970 (UTC). The Timestamp Converter supports both seconds and milliseconds. Enter a timestamp (seconds or ms) to get the date/time, or pick a date/time to get the timestamp. Timezone can usually be set. Conversion runs in your browser; your timestamps and dates are not uploaded or stored. Use it to debug APIs that return timestamps, convert log times, or generate timestamps for scripts and configs.

Key Features

• Seconds and milliseconds — Yes. Both seconds and milliseconds timestamps are supported.
• Bidirectional — Enter a timestamp to get the date/time, or pick a date/time to get the timestamp. Timezone can usually be set.
• Input — Enter a timestamp (seconds or ms) to get the date/time, or pick a date/time to get the timestamp. Timezone can usually be set.
• Privacy — Conversion runs in your browser. Your timestamps and dates are not uploaded or stored.
• No account — Use as often as you need without sign-up.
• Timezone — Timestamps are UTC by default. Check timezone setting. Also ensure you are using seconds vs milliseconds (10 digits vs 13) as expected if your date looks wrong.

How to Use the Timestamp Converter

1. Open the Timestamp Converter tool.
2. Enter a Unix timestamp (seconds or ms) to see the date/time, or pick a date/time to get the timestamp. Set timezone if needed.
3. Copy the result. Use the "Use tool" button on the docs page if you are reading this from the documentation.

Real Use Cases

• Debug APIs — APIs often return timestamps. Paste the value and see the human-readable date/time. Verify timezone and seconds vs ms.
• Convert log times — Logs may show epoch seconds or ms. Convert to local time for reports or tickets.
• Generate timestamps — Pick a date/time and get the timestamp for use in scripts, configs, or API requests.
• Teaching — Explain Unix time and timezones. Show 10 vs 13 digits (seconds vs milliseconds).
• Support — Convert a user-reported timestamp to a readable time for debugging.
• Cron and scheduling — Get the timestamp for "next run" or "last run" when working with Cron Expression Reader.

Why Use the Timestamp Converter Instead of Alternatives?

• vs. Color Converter — Color Converter converts colors. This tool converts time. Different domain.
• vs. Unit Converter — Unit Converter converts length, weight, etc. This tool converts time representation. Use both as needed.
• vs. JSON Formatter — JSON Formatter formats JSON. This tool converts timestamps. Different purpose.
• vs. Scripts — No coding. Works in any browser.

Timestamps are UTC by default. Check timezone setting. Also ensure you are using seconds vs milliseconds (10 digits vs 13) as expected.

Benefits for Developers, DevOps, and Support

• Developers — Quick timestamp ↔ date conversion for APIs and logs.
• DevOps — Interpret log timestamps and set up time-based configs.
• Support — Convert user-reported timestamps to readable times.

Common Mistakes

• Date wrong — Timestamps are UTC by default. Check timezone setting. Also ensure you are using seconds vs milliseconds (10 digits vs 13) as expected.
• Wrong digit count — 10 digits = seconds. 13 digits = milliseconds. Mixing them gives the wrong date.
• Expecting timezone in timestamp — Unix timestamp is always UTC. The tool converts to a timezone for display.
• Forgetting to copy — The result is not saved. Copy before closing the tab.
