There should be a datetime_format option to specify whether the date or the time comes first

As a theme author it would be very useful to have a global option for formatting a full datetime (and a the_datetime() function too).

Sometimes datetimes are formatted "$date $time", sometimes it's "$time $date", sometimes it's even "$date at $time".

I think there should be an option for this in the general settings alongside the date and time format options.
