This should be BIN2BCD(dt->tm_mon + 1)) instead. Otherwise, in october (month 9), the final value will be 0xa instead of 0x10.

Other than that, the patch looks fine to me. You can add
Acked-by: Raphael Assenat <raph@xxxxxx> to the updated patch.

Please add Alessandro Zummo <a.zummo@xxxxxxxxxxxx> in the CC list to make sure he sees it.
