About UNIX Timestamps

A UNIX timestamp (also known as epoch time) is the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC (Coordinated Universal Time). This date is known as the "UNIX epoch" and serves as a reference point for measuring time in computer systems.

Key Features

  • Universal Standard: UNIX timestamps are used across different operating systems and programming languages
  • Precise: Represents time down to the second (or millisecond for some implementations)
  • Timezone Independent: Always in UTC, making it easy to convert to any timezone
  • Compact: A single integer represents a specific point in time
  • Sortable: Larger numbers represent later times, making them easy to sort

Common Use Cases

  • Database Storage: Storing timestamps in databases for efficient querying
  • API Development: Using timestamps in REST APIs and web services
  • Log Files: Recording events with precise timestamps
  • File Systems: Tracking file creation, modification, and access times
  • Version Control: Git and other version control systems use timestamps
  • Analytics: Tracking user behavior and system performance over time

How to Use This Converter

Converting UNIX Timestamp to Date:

  1. Enter a UNIX timestamp in the "UNIX Timestamp" field
  2. Click "Convert to Date" or wait for automatic conversion
  3. View the results in multiple formats (UTC, Local Time, ISO 8601)

Converting Date to UNIX Timestamp:

  1. Select a date and time in the "Date & Time" field
  2. Click "Convert to Timestamp" or wait for automatic conversion
  3. Get the corresponding UNIX timestamp

Important Notes

  • Year 2038 Problem: 32-bit systems will have issues after January 19, 2038, when the timestamp exceeds 2,147,483,647
  • Milliseconds vs Seconds: Some systems use milliseconds (13 digits) instead of seconds (10 digits)
  • Timezone Considerations: Always be aware of timezone differences when working with timestamps
  • Leap Seconds: UNIX timestamps don't account for leap seconds, but this rarely affects most applications

Programming Examples

// JavaScript
const timestamp = Math.floor(Date.now() / 1000); // Current timestamp
const date = new Date(timestamp * 1000); // Convert back to date

// Python
import time
timestamp = int(time.time())  # Current timestamp
date = time.localtime(timestamp)  # Convert back to date

// PHP
$timestamp = time();  // Current timestamp
$date = date('Y-m-d H:i:s', $timestamp);  // Convert back to date

// Java
long timestamp = System.currentTimeMillis() / 1000;  // Current timestamp
Date date = new Date(timestamp * 1000);  // Convert back to date
