Wow, that's a lot.
could this have something to do with dynamic cpu frequency scaling?
I doubt it. The clock is a hardware thing. It is powered by the bios battery and is independent of the computer. The system reads the time from the bios. The clock provides 'ticks' to the operating system by interrupt so the system clock can be updated.
If your clock is running so slow it will be hardware related. Minutes per hour is broken and should probably be treated as a fault. You should expect drift within 1:10^5 or about 1sec per day.
I suggest you boot into the bios and monitor the clock there to get an idea of the raw timekeeping ability over say 24h.
