What's a Unix Timestamp?
A Unix timestamp is the number of seconds elapsed since January 1, 1970 00:00:00 UTC (the 'epoch'). So '1700000000' = November 14, 2023, 22:13:20 UTC. Used universally in computing for date storage, log files, database timestamps, and time arithmetic.
Convert a timestamp to readable date by adding it as seconds to the epoch. A 32-bit Unix timestamp can represent dates up to January 19, 2038 (the 'Year 2038 problem'). Modern systems use 64-bit timestamps avoiding this. Most programming languages have built-in functions: Date(timestamp * 1000) in JavaScript (which uses milliseconds), datetime.fromtimestamp() in Python.

Frequently Asked Questions
Why does Unix start from 1970?
Arbitrary choice by Unix designers in early 1970s. They needed a reference point; January 1, 1970 was rounded up from the Unix system creation date. The epoch has stuck for 50+ years and is now embedded in countless systems.
What's the Year 2038 problem?
32-bit signed integer Unix timestamps overflow at 2,147,483,647 seconds = January 19, 2038. After that, the value wraps to a negative number, breaking 32-bit systems. Fix: 64-bit timestamps (handles dates billions of years out). Modern systems (Linux, macOS) already use 64-bit; some embedded systems still vulnerable.
