Make the %s format (seconds since the epoch) work for a negative number and when used with a zero-padded field width, e.g. %015s. (my_strftime): Move the `do_number_sign_and_padding' label so that it precedes the code to set `digits'. Otherwise, %0Ns wouldn't work. Before this change, `date -d @-22 +%05s' would print `00-22'. Now, it prints `-0022', as it should.
