#12260: Bug: time_fmt does not support for wchar_t on windows
------------------------------+---------------------
 Reporter:  l_ting@…          |      Owner:  viboes
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  chrono
  Version:  Boost 1.59.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+---------------------
 chrono time_fmt does not support wchar_t on Windows platform. The reason
 is:

 In the constructor of ios_base_data_aux, the time_fmt and duration_fmt has
 been initialized as char_t which causes the visual studio to report
 errors. These initialization is unnecessary. As a result, comment these
 two lines of initialization resolves the issue.

         ios_base_data_aux() :
           time_fmt(""),
           duration_fmt("")
         {}
