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 alternate representations if available, or
O to use the locale's alternate numeric symbols if available.
Specifies the timezone, unless overridden by command line parameters.
If neither is specified, the setting from /etc/localtime is used.
