Merged in toggled time entry from tarruda/bootstrap-datetimepicker

This change merges in a workflow I needed from tarruda/bootstrap-datetimepicker which is now a defunct project. Specifically, when enabled, this adds a time input toggle that lets you manually specify a time to the second with spinners rather than selecting in five minute increments. I'm not sure if this change is desirable to anyone else, but, if it is, I am happy to add additional documentation to support the change or to clean up anything that isn't desirable
