In my dashboard, how to set the default latest time based on earliest time from a URL?

[exmuzzy]

I have time input in my dashboard:

<input type="time" token="trxTime">
 </input>

If I open dashboard with URL ...&form.trxTime.earliest=1488056400 then I get earliest=1488056400 and latest=now

How can I automatically set latest=earliest + 2d
without using URL ...&form.trxTime.latest=XXX

Something like that:

    <input type="time" token="trxTime">
      <default>
        <latest>$trxTime$ + 2d</latest>
      </default>
    </input>

I believe that you need to use a token to calculate the value that you need. Here is a link to Token usage in dashboards, which has a lot of reference information. If trxTime is in Linux epoch time (which appears to be true), you can calculate a new token $latestTime$

<eval token="latestTime">relative_time($trxTime$,"+2d")</eval>

You may want to use something like this in combination with the tokens described in the subsection "Define tokens for time inputs" on the same page. Hopefully, this section will get you started.

       <default>
         <latest>$latestTime$</latest>
       </default>
     </input>
