Unix timestamps represent a moment in time as the number of seconds (or milliseconds) elapsed since January 1, 1970 00:00:00 UTC. They are the standard way to store and transmit dates in APIs, databases, and log files. These tools convert between Unix timestamps and human-readable dates, generate the current epoch time, and convert timestamps to local timezone-aware date strings.
A Unix timestamp is an integer counting seconds elapsed since the Unix epoch (January 1, 1970, 00:00:00 UTC). It is timezone-independent, making it the standard for cross-platform date storage.
Most Unix timestamps count seconds. JavaScript's Date.now() returns milliseconds. Divide by 1000 to convert milliseconds to seconds, or multiply seconds by 1000 for JavaScript.
32-bit Unix timestamps overflow on January 19, 2038 (the Year 2038 problem). Modern systems use 64-bit timestamps which won't overflow for billions of years.
