I'm still looking to see if there's a generic way to determine the file-system time resolution. I have seen stated multiple places that FAT/FAT32 is limited to a time resolution of 2 seconds. For example <a href="http://docs.python.org/library/os.html#os.stat">http://docs.python.org/library/os.html#os.stat</a> says:<br>
<div class="admonition note">
<p class="first admonition-title">Note</p>
<p class="last">The exact meaning and resolution of the <tt class="xref docutils literal"><span class="pre">st_atime</span></tt>, <tt class="xref docutils literal"><span class="pre">st_mtime</span></tt>, and
<tt class="xref docutils literal"><span class="pre">st_ctime</span></tt> members depends on the operating system and the file system.
For example, on Windows systems using the FAT or FAT32 file systems,
<tt class="xref docutils literal"><span class="pre">st_mtime</span></tt> has 2-second resolution, and <tt class="xref docutils literal"><span class="pre">st_atime</span></tt> has only 1-day
resolution. See your operating system documentation for details.</p>
</div><br>I'm not sure about the "on Windows" part--whether they mean that for example linux provides 1sec emulation for FAT drives? I haven't found any support for that yet. Because removable media often uses FAT, perhaps the default should be 2 sec?<br>
