Common mistake: new Date(2145916800) in JavaScript

JavaScript's Date constructor takes milliseconds. Passing the seconds value as-is asks Date to interpret it as 2,145,916,800 ms — only a few weeks past the epoch. The result lands in early 1970.

• Right: new Date(2145916800 * 1000) → 2038-01-01T00:00:00.000Z
• Wrong: new Date(2145916800) → 1970-01-25T20:05:16.800Z
• Quick rule: a 10-digit number is seconds; a 13-digit number is milliseconds.
