The standard calendar in MS Project has a slight difference from the standard calendar that comes across from Flying Logic. It would be nice if these would be exactly the same.
Specifically, the difference is in the working time show in the Standard calendar. In MS Project, the working time is 8am-Noon and 1pm-5pm for a total of 8 hours. In the projects I get from Flying Logic, the working time is 8am-4pm for 8 hours again. This causes minor nuisances in working in MS Project.
