The first listen on http://listenbrainz.org/user/Mineo is currently

Martin O'Donnell & Michael Salvatori We Remember about 2 hours ago

but I just listened to this track to test LB-9. 2 hours is also the time difference between my local time zone (CEST) and UTC.

The HTML on http://www.last.fm/de/user/DasMineo/library is

<td class="chartlist-timestamp">
<span title="Donnerstag, 17. Sep 2015, 9:07">vor 9 Minuten</span>
</td>

("vor 9 Minuten" = "9 minutes ago").
