DateTimeFormatter::format bug?

below code : Code: Select all    int tzd=Poco::Timezone::tzd();
   cout<<tzd<<endl;
   Poco::Timestamp now;
        cout<<Poco::DateTimeFormatter::format(now,Poco::DateTimeFormat::SORTABLE_FORMAT)<<endl;   //test1
   cout<<Poco::DateTimeFormatter::format(now,Poco::DateTimeFormat::SORTABLE_FORMAT,tzd)<<endl;  //test2

the test1 is same to test2 ? maybe the tsz parameter has no effect. why? sgsoft Posts: 5 Joined: 03 Jul 2010, 12:26

DateTimeFormatter does not do local time calculation. The optional tzd is only used when the respective format specifier (%z or %Z) is present. To format a proper local time, pass an instance of Poco::LocalDateTime to DateTimeFormatter.
