Youʼre not alone, I have these too. The earliest one I have is from
September 5th at 09:01 GMT+2. Also

    auto-save-list-file-prefix is a variable defined in `startup.el'.
    Its value is "auto-save-list/.saves-"
    Original value was 
    "~/.emacs.d/auto-save-list/.saves-"

I donʼt have anything touching that variable in my init files, so
presumably something in startup.el is changing it.
