- Install the 'Maintenance' app
- Create a maintenance request, set a day and a duration of 6 hours
- Go the calendar view, month mode
- Move the maintenance request from one day to another
The duration is changed with a non-sense value.
In month mode, the hours are not represented in the calendar so it is
not possible to compute the `date_delay`. Moreover, when a record is
moved from one date to another (`_onDropRecord`) in month mode, there is
actually no point recomputing the duration; the `date_start` is enough.
Note that `date_delay` is used (at the time of writing) in 2 views and
absolutely not tested.
