So…
Your hardware clock is set to your local timezone (the “LOCAL” in /etc/adjtime). This is normal when it’s dual-boot.
And whenever you boot Windows, your hardware clock may get reset, thus confusing Debian the next time you boot Debian. But you say you don’t boot Windows very often, so…
I’m not sure whether either of these facts can explain the symptoms you’re seeing. In particular, if you’re seeing “superblock time in the future” without ever having booted Windows in between, neither of those facts would likely be involved.
One thing that does occur to me is this: If your machine is more than a few (five or so) years old, the battery (that keeps the hardware clock running when the machine is powered off) may be getting tired. It may need to be replaced. If you’re not comfortable with opening up the case yourself, maybe you’ve got a hardware hacker friend who could help?
NB: Please ignore the above paragraph if this is a laptop. The battery situation with a laptop is *entirely* different.
If you have a reliable Internet connection, you should probably think about installing ntp. It won’t do anything to fix your hardware clock, but at least it will keep your system clock synchronized to the rest of the Internet.
Enjoy!
