#7572: boost::gregorian::to_tm() does not fill in tm_gmtoff and tm_zone fields of
the resulting std::tm structure

     Type:  Bugs               |      Status:  new       
Milestone:  To Be Determined   |   Component:  date_time 
  Version:  Boost 1.52.0       |    Severity:  Problem   
 Keywords:                     |  
-------------------------------+--------------------------------------------
 On Fedora 15 (and maybe on other OSes), std::tm contains fields describing
 the time zone:

 {{{
 #ifdef  __USE_BSD
   long int tm_gmtoff;           /* Seconds east of UTC.  */
   __const char *tm_zone;        /* Timezone abbreviation.  */
 #else
   long int __tm_gmtoff;         /* Seconds east of UTC.  */
   __const char *__tm_zone;      /* Timezone abbreviation.  */
 #endif
 }}}

 boost::gregorian::to_tm() (and boost::posix_time::to_tm() respectively)
 does not fill in these fields. So these fields contain garbage. Other code
 can be misleaded with values of these uninitialized fields.
