About & methodology
epoch2038.com is an independent reference on the Year 2038 problem: what breaks when 32-bit Unix time overflows at 03:14:07 UTC on 19 January 2038, what is already fixed, and what to do about the rest. It also covers related date limits (GPS week rollover, the NTP 2036 era, 2106) and what the Y2K effort teaches.
How entries are researched
- Primary sources first: vendor advisories, CVEs, CERT and CISA notices, release notes, source code and standards. Press coverage is used to find leads, then checked against the original.
- Every claim is cited. Each topic page ends with numbered references, and inline [n] markers point to them.
- Unverified means unverified. Where a claim could not be confirmed from a primary source, the page says so, and the claim is not used to set a register status.
- Review dates: each topic page shows when it was last reviewed. The register was last reviewed 2026-10-21.
What the register labels mean
| At risk | Fails at or before its deadline unless something is changed. |
|---|---|
| Depends | Safe only with a particular version, build or setting. Check yours. |
| Different deadline | Not hit in 2038, but has another date limit. |
| Not affected | Not affected by the 2038 overflow. The reason is given. |
| Confirmed | Vendor advisory, CVE, documented limit or demonstrated failure. |
| Likely | Class-level assessment: typical stacks and lifetimes put it at risk, but no public failure for a specific product yet. |
Corrections
If you have evidence that changes an entry, such as an advisory, a fix, a test result or a vendor statement, please email info@epoch2038.com with a link to the source. Corrections are made on the evidence, whoever sends them.
Independence and funding
The site is free to read. It may be funded by sponsorship and by help enquiries, including referrals to specialists. Neither affects what the register says. Sponsors are listed openly, sponsor links are marked as sponsored, and any entry about a sponsor's own products says so.
