Frequently Asked Questions

What is a Unix timestamp?

A Unix timestamp (also called Epoch time) represents the number of seconds elapsed since January 1, 1970 at 00:00:00 UTC. It is widely used in programming for time storage and calculations because it is timezone-independent and easy to compare.

What is the difference between Unix timestamps in seconds and milliseconds?

Standard Unix timestamps count seconds since the epoch (10 digits, e.g., 1700000000). JavaScript’s Date.now() returns milliseconds (13 digits, e.g., 1700000000000). Our converter auto-detects the format and handles both correctly.

What is the Year 2038 problem for Unix timestamps?

On January 19, 2038, 32-bit signed Unix timestamps will overflow, resetting to negative values. Systems using 32-bit integers for time storage will break. Modern systems use 64-bit integers, which are safe for billions of years.
