By default, date pads numeric fields with zeroes. The following
optional flags may follow `%':
- (hyphen) do not pad the field
_ (underscore) pad with spaces
0 (zero) pad with zeros
^ use upper case if possible
# use opposite case if possible
After any flags comes an optional field width, as a decimal number;
then an optional modifier, which is either E to use the locale's alter‐
nate representations if available, or O to use the locale's alternate
numeric symbols if available.
