     The ssttrrffttiimmee() function formats the information from _t_i_m_e_p_t_r into the
     buffer _b_u_f according to the string pointed to by _f_o_r_m_a_t.

     The _f_o_r_m_a_t string consists of zero or more conversion specifications and
     ordinary characters.  All ordinary characters are copied directly into
     the buffer.  A conversion specification consists of a percent sign
     ```%''' and one other character.

     No more than _m_a_x_s_i_z_e characters will be placed into the array.  If the
     total number of resulting characters, including the terminating null
     character, is not more than _m_a_x_s_i_z_e, ssttrrffttiimmee() returns the number of
     characters in the array, not counting the terminating null.  Otherwise,
     zero is returned.

     Each conversion specification is replaced by the characters as follows
     which are then copied into the buffer.

     %%AA    is replaced by the full weekday name.

     %%aa    is replaced by the abbreviated weekday name, where the abbreviation
           is the first three characters.

           is replaced by the abbreviated month name, where the abbreviation
           is the first three characters.

     %%mm    is replaced by the month as a decimal number (01-12).

           of the week) as a decimal number (00-53).

     %%WW    is replaced by the week number of the year (Monday as the first day
           of the week) as a decimal number (00-53).
