Hello

I think I may have found a bug in the clocktable report: When using
:formula %, it seems days are ignored in time percentage calculation.

I have attached a simple test.org which demonstrates this.

Emacs version: 24.5.1
Org version: Org mode version 9.0.2 (9.0.2-10-g820d1e-elpa @ ~/.emacs.d/elpa/org-20161223/)

Thanks & best regards,
Andreas
