So is the Rockchip device counting incorrectly, or is someone actually proposing there is something specifically wrong with the Gregorian calendar? Without any other Google results for &quot;Rockchip calendar&quot; I&#x27;m assuming it&#x27;s the former, but if so the level of snark is a bit difficult to read through and the post doesn&#x27;t make much of a differentiation between the hardware and the calendar model used to correct for its error.
