[Cppcms-users] date_time and as::time_zone question

[Heiko W. <he...@we...>]

Hi Artyom,

first, thanks for the work, I am really impressed about what I've discovered so far !

I am just trying to figure out what parts of "boost" are still accessable with booster ... so, maybe the following is just not working by intention? I hope you can give me some enlightment ;)

This one results in an exception:

terminate called after throwing an instance of 'std::bad_cast'
 what():  std::bad_cast
Abort trap

---

#include <booster/locale/date_time.h>
#include <booster/locale/formatting.h>
#include <booster/locale/generator.h>
#include <booster/locale/localization_backend.h>
#include <iostream>
#include <sstream>

int main() {

   booster::locale::localization_backend_manager my = booster::locale::localization_backend_manager::global();
   // Get global backend

   my.select("icu");

   std::string tz = "Canada/Eastern";
   booster::locale::date_time dt;

   std::istringstream is("1999-04-22 12:13:14");
   is >> booster::locale::as::ftime( "%Y-%m-%d %H:%M:%S" ) >> dt;
   std::cout << booster::locale::as::time_zone(tz) << booster::locale::as::ftime( "%Y-%m-%d %H:%M:%S" ) << dt << std::endl;
}

I also also tried it without the backend select, but same result. The throw happens at the constructor of dt, shouldn't it work without setting up a calendar/locale first ?

Thanks in advance.
Heiko
