<p>wasn't time_t 64-bit on the amd64 ABI in first place?</p><p>(reading <a href="https://wiki.debian.org/ReleaseGoals/64bit-time" target="_blank" rel="nofollow noopener noreferrer" translate="no"><span class="invisible">https://</span><span class="ellipsis">wiki.debian.org/ReleaseGoals/6</span><span class="invisible">4bit-time</span></a>)<br />> glibc 2.34 provides support for both the existing 32-bit ABI/API and a new 64-bit ABI/API. However it does not provide a switch forcing use of the new API/ABI - each build/package chooses explicitly to use the 64bit API/ABI (by setting _TIME_BITS=64).</p><p>computers were a mistake</p>
