.TH HWCLOCK 5 "Feb 2012" "" "Debian Administrator's Manual" .SH NAME hwclock \- variables that affect the behaviour of the hwclock boot script .SH DESCRIPTION The .I /etc/default/rcS file contains variable settings in POSIX format: .IP "" .5i VAR=VAL .PP Only one assignment is allowed per line. Comments (starting with '#') are also allowed. .SH OPTIONS The following variables can be set. .IP \fBBADYEAR\fP This is used to specify that the hardware clock is incapable of storing years outside the range of 1994-1999. Set to \fByes\fP if the hardware is broken or \fBno\fP if working correctly. .IP \fBHWCLOCKACCESS\fP If the hardware clock is not accessible, set to \fBno\fP, in which case hwclock will not be run. Otherwise, set to \fByes\fP. .IP \fBHWCLOCKPARS\fP Additional options for hwclock. Unset by default. For example, this may be use to specify the machine hardware clock type for Alphas. .IP \fBHCTOSYS_DEVICE\fP The hardware clock device you want to use. Defaults to \fBrtc0\fP. It should probably match the CONFIG_RTC_HCTOSYS_DEVICE kernel config option. .SH AUTHOR Roger Leigh <rleigh@debian.org> .SH SEE ALSO .BR hwclock (8), .BR rcS (5).
