What is a Unix timestamp?

A Unix timestamp is the number of seconds that have elapsed since January 1, 1970 00:00:00 UTC. It is a common way to represent time in computing.

What is the difference between seconds and milliseconds?

A timestamp in seconds has 10 digits (e.g., 1700000000), while milliseconds has 13 digits (e.g., 1700000000000). JavaScript's Date.now() returns milliseconds.

What is the Year 2038 problem?

32-bit systems store timestamps as signed 32-bit integers, which overflow on January 19, 2038. Most modern systems use 64-bit integers to avoid this.
