Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp (also called epoch time or POSIX time) is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC. It's a simple, universal way to represent a point in time as a single number, widely used in programming, databases, and APIs.
What is the difference between seconds and milliseconds?
Traditional Unix timestamps are in seconds (10 digits, e.g. 1700000000). JavaScript's
Date.now() and some APIs return milliseconds (13 digits, e.g. 1700000000000), which is 1000x larger and provides sub-second precision.What is the Year 2038 problem?
32-bit systems store Unix time as a signed 32-bit integer, which can only represent dates up to January 19, 2038 03:14:07 UTC before overflowing. Most modern systems now use 64-bit integers, which won't overflow for another 292 billion years.
What time zone does this use?
Unix timestamps are always UTC. The human-readable dates shown here are displayed in your local browser time zone, with the UTC equivalent also shown for reference.
