Setting the proper TimeZone at application start-up

In order to use Wt::WLocalDateTime, you must set in a proper time-zone inside the application locale. The following codes will aid in setting the locale with a proper time-zone and perhaps custom date formatting and so on.

148   #include <chrono>
149   #include <Wt/Date/tz.h>
150
151   //
152   // set the time-zone to the proper format
154   //
155   auto loc = locale();
156
157   auto tz = date::locate_zone( environment().timeZoneName() );
158
159   loc.setTimeZone( tz );
160
161   std::cout << __FILE__ << ":" << __LINE__
162     << " tzn:" << environment().timeZoneName()
163     << " tzo:" << environment().timeZoneOffset().count()
164     << " tz:" << tz
165     << " loc:" << loc.name()
166     << " ltz:" << loc.timeZone()-> name()
167     << std::endl;

151   //
152   // set the date format to regular american
154   //
169   loc.setDateFormat( "MM/dd/yyyy" );
170   setLocale( loc );
171
172 } // endvoid MyProject::AppBase::init( )
