[O] Time calculation: vsum?

[Christian Moe]

Hi,

Time calculations don't seem to work with vsum (or vmean).


|    Time |
|---------|
| 1:06:00 |
| 0:52:30 |
| 2:00:00 |
|---------|
|       3 |
#+TBLFM: @5$1=vsum(@I..@II);T


Am I doing something wrong?

Could this be made to work?

Yours,
Christian
