There are problems in KDE 4.3 calculation. In KDE 4.4
America/New York|DateTime=2009-11-24T12:00:00|Solar|Latitude=40|Longitude=-75
Gives:
Sunrise: QVariant(QDateTime, QDateTime("Tue Nov 24 06:55:32 2009") )
Sunset: QVariant(QDateTime, QDateTime("Tue Nov 24 16:37:55 2009") )
And noaa for the same time zone:
Sunrise: 06:56
Sunset: 16:38
