20 # Note the weird semantics if hwclock and the kernel here: the first
21 # settimeofday() invocation from userspace is special and may be used
22 # to set the offset from UTC of the system clock. It is independent
23 # of any specific RTC device. This is mostly a crufty hack to support
24 # legacy operating systems which insist on storing local time in the
27 # Note that we do not run --hctosys here, we assume the kernel
28 # includes a compiled in RTC module which is used to initialize the
29 # system time as part of kernel setup.
