time_tfield held, as many implementations do, in a 32-bit signed integer, which exhausts its range 2^31 − 1 seconds past the 1970 epoch — at 03:14:07 UTC on 19 January 2038 — and wraps negative the next second; POSIX itself requires only thattime_tbe an integer type, so the width and signedness are an implementation choice.This sourceDefines `time_t` as an integer count of Seconds Since the Epoch (1970-01-01T00:00:00Z) and requires only that it be an integer type - exactly the limit the sentence attributes to it, the 32-bit signed width and the 2038 instant being implementation practice and arithmetic from 2^31 - 1.

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Read against the text for 1 of 1 citation: 1 supported. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
