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:
- Enter a UNIX timestamp in the "UNIX Timestamp" field
- Click "Convert to Date" or wait for automatic conversion
- View the results in multiple formats (UTC, Local Time, ISO 8601)
Converting Date to UNIX Timestamp:
- Select a date and time in the "Date & Time" field
- Click "Convert to Timestamp" or wait for automatic conversion
- 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
