My machine seems to be having problems with its clock. Linux keeps resetting the RTC to minus one hour. The desktop is currently showing the time as 10:46 for example.
If I run timedatectl, it shows this :-

Just before I booted into linux (the machine dual boots between Mageia 5 and Windows 7) I set the time in the BIOS to be 11:43 but I see that it's changed already.
Does anybody have any ideas what's going wrong, and more importantly how to fix it?
It's been a while since I dual booted anything but last I checked Windows stores the RTC in local time and Linux uses UTC (see "RTC in local TZ" in your timedatectl output). You need to tell Mageia that the RTC is in local time so it doesn't reset it on you.
