set-local-rtc [BOOL]
Takes a boolean argument. If "0", the system is configured to
maintain the RTC in universal time. If "1", it will maintain the
RTC in local time instead. Note that maintaining the RTC in the
local timezone is not fully supported and will create various
problems with time zone changes and daylight saving adjustments. If
at all possible, keep the RTC in UTC mode. Note that invoking this
will also synchronize the RTC from the system clock, unless
--adjust-system-clock is passed (see above). This command will
change the 3rd line of /etc/adjtime, as documented in hwclock(8).
