<p>You almost certainly want to be using a <a href="naive/struct.NaiveDate.html" title="NaiveDate"><code>NaiveDate</code></a> instead of this type.</p>
<p>This type primarily exists to aid in the construction of DateTimes that
have a timezone by way of the <a href="offset/trait.TimeZone.html" title="TimeZone"><code>TimeZone</code></a> datelike constructors (e.g.
<a href="offset/trait.TimeZone.html#method.ymd" title="TimeZone::ymd"><code>TimeZone::ymd</code></a>).</p>
<p>This type should be considered ambiguous at best, due to the inherent lack
of precision required for the time zone resolution.</p>
<p>There are some guarantees on the usage of <code>Date&lt;Tz&gt;</code>:</p>
<ul>
<li>
<p>If properly constructed via <a href="offset/trait.TimeZone.html#method.ymd" title="TimeZone::ymd"><code>TimeZone::ymd</code></a> and others without an error,
the corresponding local date should exist for at least a moment.
(It may still have a gap from the offset changes.)</p>
</li>
<li>
<p>The <code>TimeZone</code> is free to assign <em>any</em> <a href="offset/trait.Offset.html"><code>Offset</code></a> to the
local date, as long as that offset did occur in given day.</p>
<p>For example, if <code>2015-03-08T01:59-08:00</code> is followed by <code>2015-03-08T03:00-07:00</code>,
it may produce either <code>2015-03-08-08:00</code> or <code>2015-03-08-07:00</code>
but <em>not</em> <code>2015-03-08+00:00</code> and others.</p>
</li>
<li>
<p>Once constructed as a full <code>DateTime</code>, <a href="struct.DateTime.html#method.date" title="DateTime::date"><code>DateTime::date</code></a> and other associated
methods should return those for the original <code>Date</code>. For example, if <code>dt = tz.ymd_opt(y,m,d).unwrap().hms(h,n,s)</code> were valid, <code>dt.date() == tz.ymd_opt(y,m,d).unwrap()</code>.</p>
</li>
<li>
<p>The date is timezone-agnostic up to one day (i.e. practically always),
so the local date and UTC date should be equal for most cases
even though the raw calculation between <code>NaiveDate</code> and <code>Duration</code> may not.</p>
</li>
</ul>
