Subject: bug#34608: date +%+4C is unimplemented, contrary to POSIX
Date: Thu, 21 Feb 2019 11:10:06 -0600

POSIX requires the '+' flag in %C to output padding with leading 0, and
additionally to add a +/- indicator if the minimum field width is larger
than 2 bytes.  Thus:

date -d 0001-01-01 +.%+4C.

should produce ".+000.", but currently it produces ".%+4C." because the
+ flag is unimplemented.
