The Effort property previously had no unit attached. With release 7.5 of orgmode you can now attach units to it such as 4h, 2d or 2m. The taskjuggler exporter however doesn't support this feature yet. It currently assumes that if is simply a number that we are talking about days. If the format is something like 5:30 it assumes that the effort is in hours:minutes. It has no support for other formats (weeks, months which taskjuggler itself would support).
Now I suppose the exporter should honor the new effort durations that were introduced in 7.5. This is not that hard to change. However this would mean that existing orgmode files will be exported differently, i.e. the change is not backwards compatible. At the moment I do not know how to deal with this. Should I just move to the new effort durations and ask the user to upgrade their orgmode files or more specifically to upgrade their effort properties to the new effort durations format? Thoughts?
