Hi,

In ADT all elements being displayed are assets, hence their title, created date, modified date , .. etc  will be available in asset entry object itself.

You can try below code in your ADT to display last modified date in required format.

<#assign dateFormat = "MM-dd-yyyy" />
<#if entries?has_content>
	<#list entries as curEntry>
		${curEntry.getTitle(locale)}<br/>
		
		${dateUtil.getDate(curEntry.getModifiedDate(), dateFormat, locale)}
	</#list>
</#if>
