Check announcements date

[Zahra]

Hi,

I'm going to change the announcements page a bit and show the newest announcements (created on last 24 hours) in a different way. How should I create my reference time (now-24hours) in the code and compare $announcement.date with this reference date?

I want to know how to change the below code in the announcements.tpl:

{foreach from=$announcements item=announcement}

    <div class="announcement-single">

        <a href="{routePath('announcement-view', $announcement.id, $announcement.urlfriendlytitle)}" class="ttitle">
			/* I want to check $announcement.date here*/
            {$announcement.title}

        </a>
