Martin,
glad to see you got further with this!
You can definitely get rid of hmconcat by using a combination of
string-to-number and format (and I'm sure it's possible to get this done
with simpler elisp):
--8<---------------cut here---------------start------------->8---
| Date | Start | Lunch | Back | End | Sum | hms | hh | mm |
|------------------+-------+-------+-------+-------+-------+-----------+----+----|
| [2011-03-01 Tue] | 08:00 | 12:20 | 13:00 | 17:00 | 08:20 | 8@ 20' 0" | 8 | 20 |
#+TBLFM: $6='(format "%02d:%02d" (string-to-number $8) (string-to-number $9))::$7=time(<2010-01-01 $5>)-time(<2010-01-01 $4>)+time(<2010-01-01 $3>)-time(<2010-01-01 $2>)::$8=hour($7)::$9=minute($7)
--8<---------------cut here---------------end--------------->8---
