Working Hours

At the moment the spec seems to suggest that you only one start time and one end time.

Is it your intention to only have one of each or do you want to allow for users to create multiple start/end times.

A use of the latter idea is for a person who wants to do 4 hours from 6am-10am and then has errands to do and then goes back to work at 2pm-6pm.

The latter feature could always be implemented later but it could effect the design of the data storage now.
