Epoch Converter

Convert Unix timestamps to human-readable dates.

Convert Unix timestamps to human-readable dates and back. Essential for debugging server logs and databases.

Why This Tool Exists

Computers track time by counting seconds since January 1, 1970 (the Unix Epoch). Humans track time with calendars. Translating `1672531200` to "Jan 1, 2023" in your head is impossible. When debugging databases, analyzing logs, or setting expiration headers, you need to seamlessly switch between these formats. PrivaQuickTools Epoch Converter offers a clean, bidirectional interface. It handles seconds, milliseconds, and microseconds, and clarifies the timezone used.

We had a bug where users were getting logged out immediately. Only after converting the token's 'exp' timestamp did we realize we were generating tokens valid for the 'past' due to a timezone math error.

Key Capabilities

Core features that make this tool powerful.

Privacy First: Files never leave your device.

Instant: No upload or download wait times.

Secure: Local processing guarantees data safety.

Free: No subscriptions or hidden fees.

How It Works

Understanding the processing logic.

A precise time translator: - **Modes:** Timestamp to Date, Date to Timestamp. - **Precision:** Detects seconds (10 digits) vs milliseconds (13 digits). - **Timezone:** Displays results in both Local Time and GMT/UTC.

Accuracy & Reliability

Standard browser-based processing logic.

Who Is This For?

Database Admins

Verify stored_at or created_at columns in raw SQL.

API Developers

Check cache-control headers and token expiration claims.

Common Mysteries & Fixes

Seconds vs Milliseconds

API timestamps in Java/JS often use milliseconds. PHP/Python often use seconds. A factor of 1000 difference breaks everything.

Year 2038 Problem

32-bit integers overflow in Jan 2038. We use 64-bit safe math (JS Numbers) to go far beyond that.

Real-World Scenarios

Quick Processing

Process files without verifying server security.

Offline Work

Use the tool without an internet connection.

We do not store, view, or upload your files. All processing happens in your browser's memory. When you close the tab, all data is wiped from memory.

Good to Know

Large files depends on your device RAM. Processing massive video/PDFs may be slower on mobile devices.

Benefits

  • Local ProcessingData stays on your machine, always.
  • No InstallationWorks instantly in your browser.
  • Zero Cost100% free and open.
  • UnlimitedNo artificial limits on file count.

When Not To Use

While we aim for perfection, browser-based tools have limits. This tool might not be the best fit for:

  • Extremely large files (e.g., video over 2GB)
  • Batch processing thousands of files at once
  • Workflows requiring server-side collaboration or cloud storage

We display both. The big bold text is usually your local time, with UTC below it.
It's when 32-bit signed integers run out of space to store seconds since 1970. Modern 64-bit systems are safe.
