       %t     a	tab

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

       %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

	      +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.

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

EXAMPLES
       Convert seconds since the epoch (1970-01-01 UTC)	to a date

	      $	date --date='@2147483647'

       Show the	time on	the west coast of the US (use tzselect(1) to find TZ)

	      $	TZ='America/Los_Angeles' date

       Show the	local time for 9AM next	Friday on the west coast of the	US

	      $	date --date='TZ="America/Los_Angeles" 09:00 next Fri'

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.
