And paste this code below the last line above:
<pre class="ip-ubbcode-code-pre"><widget class="date_cell" id="date" text="date" standard_spec="text" style="shadowed" alignment="top, right" auto_size="vertical"> <attachment class="get_global_attachment" get_property="date" set_property="valu"/> <attachment class="test_global_attachment" get_property="cont" value="-8" set_property="hidn" skip_if_null="false" skip_if_resetting="false" priority="1"/> <attachment class="get_global_attachment" get_property="fcol" set_property="colr"/> <string id="format"> [%date#1-day] [%date#1-time] [%date#1-long_no_day] </string> </widget></pre>
