What is a Unix Timestamp?
A Unix timestamp is the number of seconds that have elapsed since January 1, 1970 UTC. Many programming languages, databases, APIs, and logging systems use timestamps because they are compact, consistent, and easy to compare programmatically. Converting them into readable dates helps when debugging and interpreting time-based data.
