NAME
       hwclock - settings that affect the behaviour of the hwclock init script


DESCRIPTION
       The /etc/default/hwclock file contains settings in POSIX format:

            VAR=VAL

       Only one assignment is allowed per line.  Comments (starting with '#') are also allowed.


SETTINGS
       The following settings can be set.

       HCTOSYS_DEVICE
              The  hardware  clock  device  you  want  to  use.  Defaults to rtc0.  It should probably match the
              CONFIG_RTC_HCTOSYS_DEVICE kernel config option.

              If  you  change   this,   you   also   need   to   install   a   custom   udev   rule,   mirroring
              /usr/lib/udev/rules.d/85-hwclock.rules.  Otherwise,  the  hardware  clock  device  will be ignored
              during boot.

              On almost all systems, this should not be changed.


NOTES
       On systems using systemd as init, the hwclock init script is ignored.
