Modern Node.js and browser JavaScript using Date and Date.now().
Complete JavaScript Recipe
// 1. Current timestamp in seconds & milliseconds
const currentSec = Math.floor(Date.now() / 1000);
const currentMs = Date.now();
// 2. Convert timestamp (1710000000) to human-readable Date
const date = new Date(1710000000000);
console.log(date.toISOString()); // e.g. "2026-10-02T03:30:00.000Z"
console.log(date.toLocaleString()); // Local timezone string
// 3. Convert ISO string or Date to Unix timestamp
const epochSec = Math.floor(new Date("2026-10-02T12:00:00Z").getTime() / 1000);
