      Set the system date and time. Each argument is an element of the date, but
      not required. If an element is not passed, the current system value for
      that element will be used. For example, if you don't pass the year, the
      current system year will be used. (Used by set_system_date and
      set_system_time)
  
      Updates hardware clock, if present, in addition to software
      (kernel) clock.
  
      :param int years: Years digit, ie: 2015
      :param int months: Months digit: 1 - 12
      :param int days: Days digit: 1 - 31
      :param int hours: Hours digit: 0 - 23
      :param int minutes: Minutes digit: 0 - 59
      :param int seconds: Seconds digit: 0 - 59
      :param str utc_offset: The utc offset in 4 digit (+0600) format with an
          optional sign (+/-).  Will default to None which will use the local
          timezone. To set the time based off of UTC use "'+0000'". Note: if
          being passed through the command line will need to be quoted twice to
          allow negative offsets.
      :return: True if successful. Otherwise False.
