How can I perform math calculations within my XML dashboard?

I would like to use a drilldown token created from clicking a bar on a timechart and add 1800 to the value and use it in the "latest" tag in the new chart that generates. Here's what I currently have:

<form>
  <fieldset submitButton="false" autoRun="true">
    <input type="time" token="field1">
      <label></label>
      <default>
        <earliest>-24h@h</earliest>
        <latest>now</latest>
      </default>
    </input>
  </fieldset>
  <row>
    <panel>
      <table>
        <search>
          <query></query>
          <earliest>$field1.earliest$</earliest>
          <latest>$field1.latest$</latest>
          <sampleRatio>1</sampleRatio>
        </search>
        <option name="drilldown">$click.$value$</option>
        <drilldown>
            <condition>
            <set token="accountNumber">$click.value$</set>
            <set token="myAccount">$click.value$</set>
          </condition>
        </drilldown>
      </table>
    </panel>
  </row>
  <row>
    <panel depends="$myAccount$">
      <title>$myAccount$</title>
      <chart>
        <search>
          <query>accountId=$accountNumber$ | timechart count()</query>
          <earliest>$field1.earliest$</earliest>
          <latest>$field1.latest$</latest>
        </search>
        <option name="charting.drilldown">all</option>
        <drilldown>
          <condition>
            <set token="timeSpan">$click.value$</set>
            **<eval token="timeSpan2">'click.value$ + 500</eval>**
          </condition>
        </drilldown>
      </chart>
    </panel>
    <panel depends="$timeSpan$">
       <chart>
        <search>
          <query>accountId=$accountNumber$ | timechart count()</query>
          <earliest>$timespan$</earliest>
          <latest>**$timeSpan2$**</latest>
        </search>
        <option name="charting.drilldown">none</option>
      </chart>
    </panel>
  </row>
</form>

I cleared out most of the fluff to make it a bit easier to read through. The $timeSpan$ token works perfectly fine but how do I add 1800 to $timeSpan$ and set that to token $timeSpan2$?

Thank you,

Jonathan

@jonx10000 ,
Try

<form>
  <label>Time Additions</label>
  <fieldset submitButton="false">
    <input type="time" token="TimeInputToken">
      <label>Time</label>
      <default>
        <earliest>-15m</earliest>
        <latest>now</latest>
      </default>
    </input>
  </fieldset>
  <row>
    <panel>
      <chart>
        <search>
          <query>index=_*|timechart count by sourcetype</query>
          <earliest>$TimeInputToken.earliest$</earliest>
          <latest>$TimeInputToken.latest$</latest>
        </search>
        <option name="charting.chart">column</option>
        <option name="charting.drilldown">all</option>
        <drilldown>
          <set token="Clicked_Earliest">$earliest$</set>
          <set token="Clicked_Latest">$latest$</set>
          <eval token="Added">$latest$+500</eval>
        </drilldown>
      </chart>
    </panel>
  </row>
  <row>
    <panel>
      <html>
        <h1>

I actually have one more question is it possible to do math operations within an eval if statement?

<eval token="timeLatestToken">if('TimeInputToken.latest'-'TimeInputToken.earliest'>86000, 'timeEarliestToken'+86400, 'timeEarliestToken'+1800)</eval>

Is it possible to perform an operation like this?

Beautiful thank you. I did attempt to add within the eval tag before but I did not realize the spaces were effecting it.
