<p><pre><code>  dmesg -T
</code></pre>
Has been available for <i>years</i> to print out human-readable timestamps. Check to see if dmesg is an alias to that on your system. Also, -IIRC- dmesg has printed system-uptime timestamps with every line since <i>at least</i> the early 2000&#x27;s.<p>One caveat: the times printed by dmesg -T will be incorrect if the system has suspended to RAM or disk.<p>Check dmesg(1) for more info! :D
