Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp (also called Epoch time) is the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC. It's a simple way to represent a point in time as a single number, widely used in programming, databases, and APIs.
What's the difference between seconds and milliseconds?
Unix timestamps in seconds are 10 digits (e.g., 1700000000), while millisecond timestamps are 13 digits (e.g., 1700000000000). JavaScript's Date.now() returns milliseconds, while many APIs and databases use seconds. This tool auto-detects and supports both formats.
What is the Year 2038 problem?
The Year 2038 problem occurs because 32-bit systems store Unix timestamps as signed 32-bit integers, which will overflow on January 19, 2038. Modern 64-bit systems and JavaScript use 64-bit numbers, so they are not affected by this limitation.
