   Thanks for the detailed analysis,  uldivmod/uidivmod not only consume more flash space, but also execute very slow. clock/timestamp is called so frequently, we have found the performance lost is noticeable in the real product, it's better to replace 64bit mul/div with 32bit counterpart for both size and performance.
