⏱️ Timestamp Converter

About Timestamp Converter

This tool helps you convert between Unix timestamps (epoch time) and human-readable dates. Unix timestamps represent the number of seconds (or milliseconds) that have elapsed since January 1, 1970, 00:00:00 UTC (the Unix epoch).

Features

• Bi-directional conversion: Convert timestamp to date or date to timestamp
• Seconds and milliseconds: Support for both timestamp formats
• Real-time conversion: See results as you type
• Current time: Quick button to use current timestamp
• Copy to clipboard: One-click copy of timestamps
• Precise time: Includes hours, minutes, and seconds

How to Use

• Timestamp to Date: Enter a Unix timestamp (in seconds or milliseconds) in the left box to see the human-readable date
• Date to Timestamp: Select a date and time in the right box to see the Unix timestamp
• Current Time: Click "Use Current Time" to populate with the current timestamp
• Copy: Use the copy buttons to quickly copy timestamps to your clipboard

What is a Unix Timestamp?

A Unix timestamp (also known as epoch time or POSIX time) is a system for tracking time as a running count of seconds. It starts from the Unix epoch: January 1, 1970, at 00:00:00 UTC. This standardized format is widely used in programming, databases, and APIs because it's timezone-independent and easy to calculate with.

Seconds vs Milliseconds

Unix timestamps can be expressed in two formats:

• Seconds: 10-digit number (e.g., 1735228800) - most common in Unix/Linux systems
• Milliseconds: 13-digit number (e.g., 1735228800000) - commonly used in JavaScript and some APIs

Common Use Cases

• Debugging API responses with timestamp fields
• Converting database timestamp columns
• Analyzing log files with Unix timestamps
• Working with JavaScript Date objects (milliseconds)
• Scheduling cron jobs and automated tasks
• Calculating time differences in applications
• Testing time-based features in development

Programming Examples

Here's how timestamps are used in different programming languages:

• JavaScript: Date.now() returns milliseconds, Math.floor(Date.now() / 1000) returns seconds
• Python: import time; time.time() returns seconds with decimals
• PHP: time() returns seconds, microtime(true) returns seconds with microseconds
• MySQL: UNIX_TIMESTAMP() returns seconds
