#1674: date_time::date_formatting.hpp: incorrectly formats year using global
locale

     Type:  Bugs                   |      Status:  new       
Milestone:  Boost 1.36.0           |   Component:  date_time 
  Version:  Boost 1.34.1           |    Severity:  Problem   
 Keywords:  locale formatting      |  
-----------------------------------+----------------------------------------
 The function boost::date_time::ymd_formatter::ymd_to_string() uses the
 ostream<<() function to write the date. This later function will use the
 current global locale to format each of the elements of the date. In
 particular, when the global locale is set to en_US, the year will be
 formatted to be 2,008 which is incorrect.

 The proposed solution is to temporarily imbue the ostream with the classic
 locale to disable formatting. The attached patch only applies this to the
 year but it would be more robust to apply to the day and month components
 as well.

 This type of error probably exists in other functions.
