<p>This template returns the start and end time for a TTML element, based on the <code>begin</code>, <code>end</code>, and <code>dur</code> attributes. It returns each of them as numbers of seconds, as returned by <code style="xslt-template" xref="ttml.time.seconds">ttml.time.seconds</code>, separated by a comma. Begin and end times are returned as absolute times, relative to the computed range of the parent element. The parent range may be passed in the <code style="xslt-param">range</code> parameter. If the parameter is empty, the parent range is computed automatically by calling this template on the nearest ancestor of <code style="xslt-param">node</code> with a <code>begin</code> attribute.</p>
<p>If both <code style="xslt-param">end</code> and <code style="xslt-param">dur</code> are provided, the end times for each are calculated, and the one that results in the shortest duration is used.</p>
<p>If there is no end time for the element, the string <code>∞</code> is used as the end time.</p>
