What is a Unix Timestamp?
A Unix timestamp (also called Epoch time) is a way to track time as a running total of seconds since the Unix Epoch on January 1st, 1970 at UTC. It's widely used in programming and databases because it represents time as a simple integer, making it easy to store and compare.

Frequently Asked Questions
Why do developers use Unix timestamps?
Unix timestamps provide a language-agnostic way to represent time. They're easy to store (just a number), compare (numerical comparison), and convert to any timezone. Most programming languages have built-in support for Unix timestamps.
What is the difference between seconds and milliseconds?
Unix timestamps in seconds count seconds since 1970. Millisecond timestamps multiply this by 1000 for more precision. JavaScript typically uses milliseconds, while many other systems use seconds.
When does the Unix timestamp overflow?
32-bit systems using signed integers will overflow on January 19, 2038 (the Year 2038 problem). Modern systems use 64-bit integers, which won't overflow for billions of years.
