Two Problems...
1. I have changed the date format in my instance of JIRA from the default to mm/dd/yyyy, but when I enter the Log Work screen, the date format of the "Date Started" screen remains the default format, e.g., "17/Sep/12." Is there a way to change this?
2. If I change the "Date Started" field to another value using the date picker, then the date displayed in the field is formatted mm/dd/yyyy (see below). But then I get the following error: "You must specify a date on which the work occurred":

It appears that the "Date Started" field is still expecting "17/Sep/12" rather than "09/17/2012" and gets angry when it doesn't get what it wants.
Thank you
