I am replying to myself in order to explain my solution. As it does not
seem to be possible to change the display format, I simply added an
elisp formula in the table (thanks to Carsten who suggested not to use
babel). The difficulty was to parse the content of the field since it's
not a number but a string with a colon in the middle.

Clock summary at [2010-03-26 ven. 17:56]

| L | Headline              | Time     |           |
|---+-----------------------+----------+-----------|
|   | *Total time*          | *528:00* | *22 days* |
|---+-----------------------+----------+-----------|
| 1 | All                   | 528:00   |           |
| 2 | Event A               |          |     72:00 |
| 2 | Event B               |          |     96:00 |
| 2 | Event C               |          |    120:00 |
| 2 | Event D               |          |    120:00 |
| 2 | Event E               |          |    120:00 |
#+TBLFM: @2$4='(concat "*" (number-to-string (/ (string-to-number (if 
(string-match "\\(.+\\):.+" @3$3) (match-string 1 @3$3))) 24)) " days*")
#+END:

Notice that the formula is kept when updating the clocktable, so it's
very easy to use.

I really needed this since I had to know the number of days spent to
theses events (the duration of a trip is naturally in days, not in
hours). I am not sure if this tips has a real interest for work, but I
can add it if you ask.

Cheers,
