[PATCH] date: Add `seconds since midnight' and `day of year (000..365)'

[Shaun Jackman]

This patch adds two useful formats to date:

        %i -- seconds since midnight
        %J -- day of year (000..365)

These formats are useful in constructing a time format which is
zero-based and includes a minimum number of arbitrary bases, such as
%Y-%J-%i.%N.

Cheers,
Shaun

        * lib/strftime.c (strftime_case_): Add %i -- seconds since midnight.
        Add %J -- day of year (000..365).
        * src/date.c (usage): Ditto.
