日出和日落计算器(Sunrise and Sunset Calculator)

日出和日落计算器(Sunrise and Sunset Calculator)

我想为凤凰城获得日出和日落时间。

我正在使用： https ： //github.com/mikereedell/sunrisesunsetlib-java

package sunriseSunsetCalculator; import java.io.IOException; import java.util.Calendar; import java.util.Date; import com.luckycatlabs.sunrisesunset.SunriseSunsetCalculator; import com.luckycatlabs.sunrisesunset.dto.Location; public class getSunriseSunet { public static void main (String[] args) throws IOException { Location location = new Location("33.4500", "-112.0667"); SunriseSunsetCalculator calculator = new SunriseSunsetCalculator(location, "Phoenix"); Date today = Calendar.getInstance().getTime(); String officialSunrise = calculator.getOfficialSunriseForDate(Calendar.getInstance()); String officialSunset = calculator.getOfficialSunriseForDate(Calendar.getInstance()); System.out.println(today + " officialSunrise : " + officialSunrise); System.out.println(today + " officialSunset : " + officialSunset); } }

产量

3月14日星期六21:35:51 MST 2015官方新闻：13：39

3月14日星期六21:35:51 MST 2015官方日历：13：39

有关日出和日落时间不正确的任何建议吗？

I am trying to get Sunrise and Sunset time for Phoenix.

I am using : https://github.com/mikereedell/sunrisesunsetlib-java

package sunriseSunsetCalculator; import java.io.IOException; import java.util.Calendar; import java.util.Date; import com.luckycatlabs.sunrisesunset.SunriseSunsetCalculator; import com.luckycatlabs.sunrisesunset.dto.Location; public class getSunriseSunet { public static void main (String[] args) throws IOException { Location location = new Location("33.4500", "-112.0667"); SunriseSunsetCalculator calculator = new SunriseSunsetCalculator(location, "Phoenix"); Date today = Calendar.getInstance().getTime(); String officialSunrise = calculator.getOfficialSunriseForDate(Calendar.getInstance()); String officialSunset = calculator.getOfficialSunriseForDate(Calendar.getInstance()); System.out.println(today + " officialSunrise : " + officialSunrise); System.out.println(today + " officialSunset : " + officialSunset); } }

output

Sat Mar 14 21:35:51 MST 2015 officialSunrise : 13:39

Sat Mar 14 21:35:51 MST 2015 officialSunset : 13:39

Any suggestion why the Sunrise and Sunset time are incorrect ?

最满意答案

我不确定您的凤凰城timeZoneIdentifier是否正确。 你可以把它换成： America / Phoenix

您也应该在正确的时区创建日历：

SunriseSunsetCalculator calculator = new SunriseSunsetCalculator(lcation, "US/Phoenix"); Calendar today = new GregorianCalendar(TimeZone.getTimeZone("US/Phoenix")); String sunrise = calculator.getOfficialSunriseForDate(today); String sunset = calculator.getOfficialSunsetForDate(today);

I am not sure if your timeZoneIdentifier for Phoenix is correct. Could you please change it to: America/Phoenix

Also you Calendar should be created in the correct time zone:

SunriseSunsetCalculator calculator = new SunriseSunsetCalculator(lcation, "US/Phoenix"); Calendar today = new GregorianCalendar(TimeZone.getTimeZone("US/Phoenix")); String sunrise = calculator.getOfficialSunriseForDate(today); String sunset = calculator.getOfficialSunsetForDate(today);
