Hello list, consider the following example:
| A | B | C | |----------+-----------+-----------| | 07:11:00 | -08:00:00 | -01:11:00 | #+TBLFM: $3=$1+$2;T I think the result in the third column is wrong. I expect 0 hours and 49 minutes, negative (-00:49:00). The following does not work, too: | A | C | |----------+-----------| | 07:11:00 | -01:11:00 | #+TBLFM: $2=$1-28800;T Daniel
