       FORMAT controls the output.  Interpreted sequences are:

       %::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.
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.
