Developer Epoch Reference & Code Snippets
JavaScript / TypeScript
Exact Formula Math.floor(Date.now() / 1000)
Date.now() returns milliseconds. Divide by 1000 to get standard 10-digit Unix timestamp seconds.
Example: new Date(1756500000 * 1000).toISOString()
Python 3
Exact Formula import time; int(time.time())
time.time() returns floating-point seconds since epoch. Cast to int for integer seconds.
Example: from datetime import datetime; datetime.fromtimestamp(1756500000)
Year 2038 Problem (Y2K38)
Exact Formula Max 32-bit Signed = 2,147,483,647
32-bit signed integers will overflow on 19 January 2038 at 03:14:07 UTC. Modern 64-bit systems are safe for 292 billion years.
Example: 2147483647 = Tue, 19 Jan 2038 03:14:07 UTC
