What is a Unix Timestamp?

A Unix timestamp (also known as Epoch time or POSIX time) is a system for describing points in time. It represents the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC (the Unix Epoch).

Unix timestamps are widely used in computing because they provide a simple, timezone-independent way to represent dates and times. They are commonly found in databases, APIs, log files, and programming languages.

How to Use This Converter

  1. Convert from timestamp: Enter a Unix timestamp in seconds or milliseconds. The converter automatically detects the format.
  2. Convert from date: Select a date and time using the date picker. The Unix timestamp is calculated automatically.
  3. Get current time: Click the "Get Current Timestamp" button to populate both fields with the current date/time.
  4. Copy results: Click any copy button to copy that specific format to your clipboard.

Timestamp Formats Explained

  • Unix (seconds) - Standard Unix timestamp with 10-digit precision (e.g., 1704067200)
  • Unix (milliseconds) - Timestamp with millisecond precision, 13 digits (e.g., 1704067200000). Commonly used in JavaScript.
  • ISO 8601 - International standard date format (e.g., 2024-01-01T00:00:00.000Z). Widely used in APIs and data interchange.
  • UTC - Coordinated Universal Time, the primary time standard (e.g., Mon, 01 Jan 2024 00:00:00 GMT)
  • Local Time - The date and time in your browser's local timezone
  • Relative Time - Human-readable time difference (e.g., "2 hours ago" or "in 3 days")

Common Use Cases

  • Debugging API responses that contain Unix timestamps
  • Converting log file timestamps to readable dates
  • Generating timestamps for database queries
  • Calculating time differences in code
  • Working with JWT token expiration times

  • Auto-detection of seconds vs milliseconds format
  • Real-time current timestamp display
  • Multiple output formats with one-click copy
  • Relative time calculation
  • Works entirely in your browser - no data is sent to any server
