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.
