       %C     century; like %Y, except omit last two digits (e.g., 20)

       %d     day of month (e.g, 01)

       %D     date; same as %m/%d/%y

       %e     day of month, space padded; same as %_d

       %F     full date; same as %Y-%m-%d

       %g     last two digits of year of ISO week number (see %G)

       %G     year of ISO week number (see %V); normally useful only with %V

       %h     same as %b

       %H     hour (00..23)

       %I     hour (01..12)

       %j     day of year (001..366)

       %k     hour ( 0..23)

       %l     hour ( 1..12)

       %m     month (01..12)

       %M     minute (00..59)

       %n     a newline

       %N     nanoseconds (000000000..999999999)

       %p     locale's equivalent of either AM or PM; blank if not known

       %P     like %p, but lower case

       %r     locale's 12-hour clock time (e.g., 11:11:04 PM)

       %R     24-hour hour and minute; same as %H:%M

       %s     seconds since 1970-01-01 00:00:00 UTC

       %S     second (00..60)

       %t     a tab

       %T     time; same as %H:%M:%S

       %u     day of week (1..7); 1 is Monday

       %U     week number of year, with Sunday as first day of week (00..53)

       %V     ISO week number, with Monday as first day of week (01..53)

       %w     day of week (0..6); 0 is Sunday

       %W     week number of year, with Monday as first day of week (00..53)

       %x     locale's date representation (e.g., 12/31/99)

       %X     locale's time representation (e.g., 23:13:48)

       %y     last two digits of year (00..99)

       %Y     year

       %z     +hhmm numeric timezone (e.g., -0400)

       %:z    +hh:mm numeric timezone (e.g., -04:00)

       %::z   +hh:mm:ss numeric time zone (e.g., -04:00:00)

       %:::z  numeric  time  zone  with	 :  to necessary precision (e.g., -04,
	      +05:30)

       %Z     alphabetic time zone abbreviation (e.g., EDT)

       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.

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  cal-
       endar  date,  time of day, time zone, day of week, relative time, rela-
       tive 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.

ENVIRONMENT
       TZ     Specifies the timezone, unless overridden by command line param-
	      eters.  If neither is specified, the setting from /etc/localtime
	      is used.
