Hi,


I am a developer of CPP and boost is my favorite library. This afternoon, I found an issue about docs of boost::gregorian::date(ver 1.63.0).

In the docs webpage(http://www.boost.org/doc/libs/1_63_0/doc/html/date_time/gregorian.html#date_time.gregorian.date_class), description as follow:

[cid:d28bb6a7-3436-4f1b-b345-86ebe1815e41]

When I used operator<< to print out the date object, there was an error from my compiler:

[cid:8d8dd812-328e-44eb-8301-5a8126f0bc60]

My code:

[cid:32c544c9-efc0-4735-837f-68179d53ba37]

Could you tell me why the compiling error happens? Thanks in advance.
