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.
DATE STRING
The --date=STRING is a mostly free format human readable date string such as "Sun, 29 Feb 2004 16:21:42 -0800" or "2004-02-29 16:21:42" or even "next Thursday". A date string may contain items indicating calendar date, time of day, time zone, day of week, relative time, relative date, and numbers. An empty string indicates the beginning of the day. The date string format is more complex than is easily documented here but is fully described in the info documentation.AUTHOR
