 21.1 `date': Print or set system date and time
 ==============================================
 
 Synopses:
 
      date [OPTION]... [+FORMAT]
      date [-u|--utc|--universal] [ MMDDhhmm[[CC]YY][.ss] ]
 
    Invoking `date' with no FORMAT argument is equivalent to invoking it
 with a default format that depends on the `LC_TIME' locale category.
 In the default C locale, this format is `'+%a %b %e %H:%M:%S %Z %Y'',
 so the output looks like `Thu Mar  3 13:47:51 PST 2005'.
 
    Normally, `date' uses the time zone rules indicated by the `TZ'
 environment variable, or the system default rules if `TZ' is not set.
  Specifying the Time Zone with `TZ' (libc)TZ Variable.
 
    If given an argument that starts with a `+', `date' prints the
 current date and time (or the date and time specified by the `--date'
 option, see below) in the format defined by that argument, which is
 similar to that of the `strftime' function.  Except for conversion
 specifiers, which start with `%', characters in the format string are
 printed unchanged.  The conversion specifiers are described below.
 
    An exit status of zero indicates success, and a nonzero value
 indicates failure.
