Hi
as you can see at https://docs.splunk.com/Documentation/Splunk/7.3.2/Viz/tokens , you can use the search tokens $job.earliestTime$ and $job.latestTime$ to add start and end time to one of the panel's title or to an html box, in the following example I added to both of them.
Something like this:
<form>
<label>test</label>
<search>
<query>| makeresults
</query>
<earliest>$Time.earliest$</earliest>
<latest>$Time.latest$</latest>
<done>
<eval token="earliestTime">$job.earliestTime$</eval>
<eval token="latestTime">$job.latestTime$</eval>
</done>
</search>
<fieldset submitButton="false">
<input type="time" token="Time">
<label>Time</label>
<default>
<earliest>-1d@d</earliest>
<latest>@d</latest>
</default>
</input>
</fieldset>
<row>
<html>
Date & Time Range Between: $earliestTime$ and $latestTime$
</html>
</row>
<row>
<panel>
<title>$earliestTime$ - $latestTime$</title>
<event>
<search>
<query>index=...</query>
<earliest>$Time.earliest$</earliest>
<latest>$Time.latest$</latest>
<sampleRatio>1</sampleRatio>
</search>
<option name="count">20</option>
<option name="list.drilldown">none</option>
<option name="list.wrap">1</option>
<option name="maxLines">5</option>
<option name="raw.drilldown">full</option>
<option name="refresh.display">progressbar</option>
<option name="rowNumbers">0</option>
<option name="table.drilldown">all</option>
<option name="table.sortDirection">asc</option>
<option name="table.wrap">1</option>
<option name="type">list</option>
</event>
</panel>
</row>
</form>
Ciao.
