Package: util-linux,linux Severity: important Tags: patch With the new armmp kernel, RTC drivers are built as modules, and thus the kernel doesn't set the system clock from the hardware clock when the module is loaded, as explained in the RTC_HCTOSYS_DEVICE KConfig option:
| The driver for this RTC device must be loaded before late_initcall | functions run, so it must usually be statically linked. In that case, util-linux should set the system clock from the RTC itself. This is correctly done through /etc/init.d/hwclock.sh when udev is not used. When using udev, the rule 85-hwclock.rules call hwclock-set, which assumes that the system clock has already been set earlier by the kernel and that the only remaining thing to do is the correct it to the local timezone (--systz). While this was true with the wheezy kernels, it's not longer true with the jessie one, and the --systohc option has to be used instead. This is the purpose of the patch below: --- util-linux-2.20.1/debian/hwclock-set +++ util-linux-2.20.1/debian/hwclock-set @@ -24,5 +24,5 @@ if [ yes = "$BADYEAR" ] ; then - /sbin/hwclock --rtc=$dev --systz --badyear + /sbin/hwclock --rtc=$dev --hctosys --badyear else - /sbin/hwclock --rtc=$dev --systz + /sbin/hwclock --rtc=$dev --hctosys fi --- util-linux-2.20.1/debian/hwclock.rules +++ util-linux-2.20.1/debian/hwclock.rules @@ -1,4 +1,4 @@ -# Reset the System Clock to UTC if the hardware clock from which it was -# copied by the kernel was in localtime. +# Set the System Time from the Hardware Clock and set the kernel's timezone +# value to the local timezone when the kernel clock module is loaded.
