Combining dates and times

Sometimes you will have separated dates and times. This is particularly frequent when they are entered by a user. From an interaction point of view, it's usually easier to pick a date and then pick a time than to pick a date and a time together. Or you might be combining inputs from two different sources.

In all those cases, you will end up with a date and a time that you want to combine in a single datetime.datetime instance.
