&gt; With Rust, we pulled time out of the standard library before 1.0, specifically because we knew it wasn&#x27;t up to the task.<p>This honestly strikes me a very good response. Saddling a still-growing community with sub-par core datatypes is worse than their absence.<p>&gt; So if &quot;no library&quot; counts as a &quot;non-broken&quot; library...<p>Of course if I had phrased my question in terms of the &#x27;first shipped date &#x2F; time library&#x27; then Rust still has a chance to follow this illustrious trajectory for languages (i.e. really mess up). :-)
