The Gantt Duration currently shows Days for the unit of measure. It looks like 0.031 days (15 mins of an 8 hr day) is the shortest duration possible when importing an MS Project file. (not 100% sure on this) When manually trying to set the duration, it looks like 0.5 Days is the shortest possible time. We have a 3 day project roll-out schedule with many single-event tasks. Many of these tasks are measured in minutes.
As an enhancement, can you make OpenProj support Hours and Minutes?
Thanks so much.
