Time tracking app 'LOGTHIS' requires a logo

C'est ce que LOGTHIS time tracking for busy people recherchait dans leur logo design

I need a clean simple logo that captures what the app is trying to do. That is be a time tracking/time sheet/work log system. Ideally I would like a logo that that is colour flexible (think the BBC logo). Initially it needs to fit with the current design of the site. See http://logthis.azurewebsites.net.
