Frequently Asked Questions

What is a Unix timestamp?

A Unix timestamp is the number of seconds that have elapsed since January 1, 1970 00:00:00 UTC (the Unix epoch). It is a simple, timezone-independent way to represent a point in time and is widely used in programming, databases, and APIs.

What is epoch time?

Epoch time is another name for Unix time. The "epoch" refers to the reference point — January 1, 1970 00:00:00 UTC — from which all Unix timestamps are measured.

What is the Y2038 problem?

The Y2038 problem occurs because many systems store Unix timestamps as a signed 32-bit integer, which overflows on January 19, 2038. Modern systems use 64-bit integers, which pushes the overflow date billions of years into the future.

Is my data sent to a server?

No. All timestamp conversions are performed entirely in your browser. No data is sent to any server.
