Support new locale key for time and date

Since different locales support different date formats, this allows
specification of the locale for a given time/date instance, rather than
setting the locale for the entire program instance and affecting all
other instances.

Note that this probably will not have much of an effect unless the
default `fmt` value is overridden (try `%c` for fun).
