<a name="details" id="details"></a><h2 class="groupheader">Detailed Description</h2>
<div class="textblock"><p>Formats simple relative dates. </p>
<p>There are two types of relative dates that it handles: </p><ul>
<li>
relative dates with a quantity e.g "in 5 days" </li>
<li>
relative dates without a quantity e.g "next Tuesday" </li>
</ul>
<p>This API is very basic and is intended to be a building block for more fancy APIs. The caller tells it exactly what to display in a locale independent way. While this class automatically provides the correct plural forms, the grammatical form is otherwise as neutral as possible. It is the caller's responsibility to handle cut-off logic such as deciding between displaying "in 7 days" or "in 1 week." This API supports relative dates involving one single unit. This API does not support relative dates involving compound units, e.g "in 5 days and 4 hours" nor does it support parsing. </p>
<p>This class is mostly thread safe and immutable with the following caveats:</p><ol type="1">
<li>The assignment operator violates Immutability. It must not be used concurrently with other operations.</li>
<li>Caller must not hold onto adopted pointers. </li>
</ol>
<p>This class is not intended for public subclassing. </p>
<p>Here are some examples of use: </p><blockquote class="doxtable">

UErrorCode status = U_ZERO_ERROR;
<a class="el" href="classicu_1_1UnicodeString.html" title="UnicodeString is a string class that stores Unicode characters directly and provides similar function...">UnicodeString</a> appendTo;
<a class="el" href="classicu_1_1RelativeDateTimeFormatter.html" title="Formats simple relative dates. ">RelativeDateTimeFormatter</a> fmt(status);
// Appends "in 1 day"
fmt.format(

// Appends "3.2 years ago"

// Appends "now"
fmt.format(UDAT_DIRECTION_PLAIN, UDAT_ABSOLUTE_NOW, appendTo, status);</pre><pre></pre> </blockquote>
<p>In the future, we may add more forms, such as abbreviated/short forms (3 secs ago), and relative day periods ("yesterday afternoon"), etc.</p>
