display time spend it hours

 Is there a way to force the Time Spent (Actual) display to only show hours?

<o:p> </o:p>

<o:p> We </o:p>  often update stories on a daily basis and find it rather annoying when Jazz decides to show time in days + hours format.  When we click on the field to change the value it gets even worse because then it switches units to days which is even less granular.

<o:p>   </o:p> Example:

<o:p> </o:p>

<o:p>   </o:p> 2 days 7 hours displayed

<o:p> </o:p>

Click on field <o:p> </o:p>

2.93 days displayed <o:p> </o:p>
