<p>Hi Eliot,</p>
<p>I don't think this is a backward compatibility issue. As mentioned, I'm using Windows 2004 (Build 19041.572), which is definitely a younger Windows version than 8.1 (which was released in 2013 compared to 2020). Microsofts and its versioning chaos :-)</p>
<p>And on my machine, time is definitively broken, or at least returning wrong values:</p>
<div class="highlight highlight-source-smalltalk"><pre><span class="pl-k">Smalltalk</span> os platformName. <span class="pl-c"><span class="pl-c">"</span>'Win32'<span class="pl-c">"</span></span>
<span class="pl-k">Smalltalk</span> <span class="pl-c1">getSystemAttribute:</span> <span class="pl-c1">1007</span>. <span class="pl-c"><span class="pl-c">"</span>'CoInterpreter VMMaker.oscog-eem.2850 uuid: 4d7fc8a4-2c7d-4bad-8aeb-5f8c5766e12a Oct 21 2020'<span class="pl-c">"</span></span>

<p><code>GetSystemTimePreciseAsFileTime</code> per se works on my machine when I try to run <a href="https://www.codeproject.com/articles/792410/high-resolution-clock-in-csharp#high-resolution-clock:~:text=High%20Resolution%20Clock,-On" rel="nofollow">this code example</a>:</p>
<pre><code>> HighResolutionDateTime.UtcNow
[2020-10-23 12:20:19]
</code></pre>
<p>Should it be relevant that I am using the 64-bit edition of Windows? However, I can reproduce the issue using both the 32-bit and the 64-bit version of OSVM.</p>
