c++ - 如何在 boost::gregorian::date 中转换 days_ 中的值

Question

我可以在 VS 的调试器中看到，boost::gregorian::date 变量包含一个成员 days_ 为 2465846.

有没有办法在纸上或 Excel 上将其转换为 dd/mm/yy？

“这几天的确切值_”当然是一个实现细节。

如果你想要一个调试可视化工具，它们是存在的，例如

• https://svn.boost.org/trac/boost/wiki/DebuggerVisualizers

  Existing visualizers

  All visualizers are available in the svn at https://svn.boost.org/svn/boost/sandbox/boost_docs/subprojects/DebuggerVisualizers. Currently, we support the following Boost types:

  • boost::array, ptr_array, ptr_deque, ptr_list, ptr_map, ptr_multimap, ptr_set, ptr_multiset, ptr_vector
  • boost::bimap
  • boost::interprocess::offset_ptr
  • boost::intrusive::list
  • boost::optional
  • boost::multi_index_container
  • boost::multiprecision
  • boost::shared_ptr
  • boost::posix_time::ptime, boost::posix_time::time_duration (two variants are available)
  • boost::regex
  • boost::variant

  There's also an unfinished visualizer for unordered containers attached to #4209. I'm not sure It isn't clear if it's possible to get it to work.

因为 ptime 聚合了一个 gregorian::date 它已经支持了。
