Set the Default Task Due Time

The default time that populates in the due date field is 5 p.m., which is after hours at my company. It would be convenient if we could set the default time to something that suits our environment, so that all new tasks will default to that specified time. While you're at it, the ability to set the default due date and reminder options rather than them being hard-coded to the following day, with no reminder, would make the tasks interface more convenient to use.
