I want to show user's last post date in profile header. so I use blow code but it doesn't work an display the same time for all users

{{if $member->member_id == \IPS\Member::loggedIn()->member_id}}
            {{$userlastpost['lastpost'] == \IPS\Member::loggedIn()->member_last_post;}}
            <li>
              <h4 class='ipsType_minorHeading'>{lang="activity_member_last_post"}</h4>
                <span>{datetime="$userlastpost['lastpost']"}</span>
            </li>
{{endif}}
