I did not but I am hoping you will manage to do it. I have already taken a quick look into org code to understand how to do it without success. For what I can understand by tracing the CLOCKSUM property usage (grep '"CLOCKSUM"' being a starting point), it seems to be doable by modifying the org-columns and org-agenda-colview-compute defuns to set a text property like org-clock-sum does with :org-clock-minutes. Then, the defun org-dblock-write:clocktable should be edited to use that property. Hope that helps. -- Konubinix GPG Key : 7439106A Fingerprint: 5993 BE7A DA65 E2D9 06CE 5C36 75D2 3CED 7439 106A
