Is it possible to know what time an ODK form was finalized upon submission?

Question

I'm creating a form that collects time specific information. Is it possible to find out what time the information was collected?

Answer 1

You can add a hidden or pre-loaded fields to your form with jr:preload and jr:preloadParams first define your instance

<instance>
   <market id="mkt">
     <colectionTime/>
   </market>
 </instance>

then bind it like this

<bind nodeset="/market/collectionTime" type="time" jr:preload="timestamp" jr:preloadParams="end"/>
