About Y2038 Problem

An independently published reference for the Year 2038 Unix time overflow, the systems still on 32-bit time, and the neighbouring 2036–2038 rollovers.

The job of this site is narrow: answer the searches operators already type, keep a structured list of related deadlines, and give a calculator for the risk window that opens before 19 January 2038.

It is not a consultancy intake form, not a vendor, and not a newsroom. Technical claims prefer vendor documentation, standards text and project maintainers over secondary blogs. Speculation is labelled.

What you will find here

• The arithmetic of signed 32-bit Unix time and why failures can happen before 2038.
• Status notes for Linux, Android, embedded systems, filesystems and databases.
• Separate records for NTP 2036, DVB-SI 2038 and the GPS week rollover — different clocks, same decade.
• A Backwards Risk calculator for install date × service life.
