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 is a widely used standard for tracking time in computing.

What is the Unix epoch?

The Unix epoch is January 1, 1970 00:00:00 UTC. This is the reference point from which Unix timestamps are measured. A timestamp of 0 corresponds to this exact date and time.

What is the difference between seconds and milliseconds timestamps?

Unix timestamps are traditionally in seconds (10 digits, e.g., 1700000000). JavaScript and some APIs use milliseconds (13 digits, e.g., 1700000000000). This tool works with seconds but also shows the millisecond value.

What is the Year 2038 problem?

The Year 2038 problem is when 32-bit Unix timestamps will overflow on January 19, 2038. Modern systems use 64-bit timestamps which will not overflow for billions of years.
