AFAIK the Linux kernel is pretty careful not to change the *hour* of the
hwclock: when using NTP, it will tweak the seconds to keep the hwclock
in sync with the rest of the world, but leave the hours alone, so as to
preserve the timezone in use, regardless if it's the right one (UTC) or
something else.
I assume GNU/Linux distributions like Debian are similarly careful,
since dual booting with a Windows install that doesn't use UTC for the
hwclock was a very common use case at least some years ago.
