NAME
       hwclock - variables that affect the behaviour of the hwclock boot script

DESCRIPTION
       The /etc/default/rcS file contains variable settings in POSIX format:

	    VAR=VAL

       Only one assignment is allowed per line.  Comments (starting with '#') are also allowed.

OPTIONS
       The following variables can be set.

       BADYEAR
	      This  is	used  to  specify that the hardware clock is incapable of storing years outside the range of 1994-1999.  Set to yes if the
	      hardware is broken or no if working correctly.

       HWCLOCKACCESS
	      If the hardware clock is not accessible, set to no, in which case hwclock will not be run.  Otherwise, set to yes.

       HWCLOCKPARS
	      Additional options for hwclock.  Unset by default.  For example, this may be use to specify the  machine	hardware  clock  type  for
	      Alphas.

       HCTOSYS_DEVICE
	      The  hardware clock device you want to use.  Defaults to rtc0.  It should probably match the CONFIG_RTC_HCTOSYS_DEVICE kernel config
	      option.
