[otrs] Last updated time / AgentDashboardTicketGeneric.dtl

Hi I have been trying to add a column to dashboard that displays the time that the ticket was last updated (AgentDashboardTicketGeneric.dtl). I have managed to add the clients name and the agents name to this display but have struck out with adding the last updated time. I have been using this as a reference http://lists.otrs.org/pipermail/otrs/attachments/20081007/3af3a951/attachmen... - but it does not address the dashboard. Any help would really be appreciated. KInd regards Mark
