Perform calculation in set tag in dynamic drilldown

[Motoko89]

Hi all, when a user clicks on a column in a chart, I want to pass custom values computed based on existing values and tokens into the link. I tried:

<drilldown>
   <set token="time_start">
       strftime($earliest|s$, "%Y-%m-%d")
    </set>
    <link>
       <![CDATA[ /app/search/report__overview#en-US/app/search/report__overview?form.input1=$time_start$&earliest=0&latest=
       ]]>
    </link>
</drilldown>

However, $time_start$ is resolved to strftime(%221457938800%22%2C%20%22%25Y-%25m-%25d%22) in the URL. How do I make Splunk perform the calculation instead?

You need to use eval instead of set:

<drilldown>
  <eval token="time_start">strftime($earliest|s$, "%Y-%m-%d")</eval>
  <link>...
