What Is a Unix Timestamp? A Complete Guide

Unix timestamps are a cornerstone of time management in programming, databases, and community platforms like Discord. This guide explores their definition, the distinction between seconds and milliseconds, and practical applications, with a free DevUtils tool to simplify conversions.

What Is a Unix Timestamp?

A Unix timestamp is the number of seconds or milliseconds since January 1, 1970, 00:00:00 UTC (Unix epoch). For example, 1694870400 represents September 16, 2023, 00:00:00 UTC. It’s a universal standard for time across platforms (Keywords: unix timestamp in seconds or milliseconds).

Seconds vs. Milliseconds

• Seconds Timestamp: 10 digits (e.g., 1694870400), ideal for most applications.
• Milliseconds Timestamp: 13 digits (e.g., 1694870400000), used for high-precision needs like real-time systems.
• Choosing the right format is key. For instance, JavaScript’s Date.now() returns milliseconds, while SQL often uses seconds.

Applications of Unix Timestamps

• 1. Programming: Track logs, event times (e.g., Python’s time.time()).
• 2. SQL Databases: Store time efficiently. MySQL’s UNIX_TIMESTAMP converts dates to timestamps (Keywords: timestamp sql).
• 3. Discord: Create dynamic timestamps that adjust to users’ timezones (Keywords: Unix timestamp for Discord).

How to Convert Date to Timestamp?

Manually calculating timestamps is complex, but DevUtils’ Timestamp Converter makes it easy:

• Enter a datetime (e.g., “2023-09-16 00:00:00”).
• Choose seconds or milliseconds, get the timestamp instantly.
• Generate Discord timestamps, e.g., <t:1694870400:F>, displaying “September 16, 2023, 00:00.”
• Keywords: convert date to timestamp, datetime to timestamp.
