Showing hours-only is something that many of our customers have asked for and is the new default behavior for FogBugz as of 7.1.5.
We made the change wholesale rather than offering a choice between days or hours for one reason: work days can be available subjective in FogBugz 7.1length, which whereas hours are not. The big problem here is currently in betathat if different people have different day lengths, they see different results. By showing only hours, it makes the time measures much less subjective.
