Hi,
many years ago a colleague and myself wrote a patch for quarters into
org-mode/clocktable for blocks, today I noticed that :step should allow
'quarter' as an argument too. Here's the tiny patch to allow that.
* doc/org-manual.org (The clock table): Document the new clocktable
option.
* lisp/org-clock.el:
(org-clocktable-steps): Add new 'quarter allowed value.
