hwclock - variables that affect the behaviour of the hwclock boot script
The /etc/default/rcS file contains variable settings in POSIX format:
Only one assignment is allowed per line. Comments (starting with
'#') are also allowed.
The following variables can be set.
- 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.
- If the hardware clock is not accessible, set to no, in which case
hwclock will not be run. Otherwise, set to yes.
- Additional options for hwclock. Unset by default. For example, this may be
use to specify the machine hardware clock type for Alphas.
- The hardware clock device you want to use. Defaults to rtc0. It
should probably match the CONFIG_RTC_HCTOSYS_DEVICE kernel config option.
