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