JavaScript Timestamp Guide: How to Get and Convert Timestamps

JavaScript is essential for web development, and timestamp handling is a key skill. This guide covers getting timestamps, converting datetime to timestamp, and vice versa, with DevUtils’ free tool for validation.

JavaScript Timestamp Basics

Unix timestamps represent time in seconds or milliseconds. JavaScript uses milliseconds by default, e.g., 1694870400000 for September 16, 2023, 00:00:00 UTC (Keywords: unix timestamp in seconds or milliseconds).

Getting Timestamps

• Milliseconds:

console.log(Date.now());  // Output: 1694870400000

• Seconds:

console.log(Math.floor(Date.now() / 1000));  // Output:1694870400

Datetime to Timestamp

Convert a date using Date:

const dt = new Date('2023-09-16');
const timestamp = dt.getTime();  // Milliseconds
console.log(timestamp / 1000);  // Seconds: 1694870400

Keywords: convert datetime to timestamp.

Timestamp to Datetime

Convert a timestamp back to a date:

const timestamp_ms = 1694870400000;
const dt = new Date(timestamp_ms);
console.log(dt);  // Output：Sat Sep 16 2023 00:00:00 GMT+0000

Keywords: convert timestamp to datetime.

Validation Tool

DevUtils’ Timestamp Converter verifies JavaScript timestamps:

• Input timestamps to check dates.
• Generate Discord timestamps (e.g., <t:1694870400:F>).
• Secure, client-side processing.
