Question

www.un.org/Depts/DGACM/index_spanish.htm 能否将浮游转换到 Java的一个时间?

http://www.webservicex.net/sunsetriseservice.asmx?WSDL"rel=“nofollow”here。

我早就通过这项服务:自由度(34.0888)、长度(-118.40612)、日、月和年,我回过了价值:

sunrise: 13.6935135 sunset: 26.607845

但是,这些数值是浮动的,谁知道为什么会出现? 或者如果能够从中抽出时间? 我认为,这可能是不错的,但我不敢这样做。

Any help is appreciated, thanks

这很可能是美洲金枪鱼委的一些小时。我试图这样做:

Calendar calendar = Calendar.getInstance(TimeZone.getTimeZone("UTC"));
calendar.set(Calendar.HOUR_OF_DAY, 0);
calendar.add(Calendar.HOUR_OF_DAY, (int) sunrise);
calendar.set(Calendar.MINUTE, (sunrise * 60) % 60);
calendar.set(Calendar.SECOND, (sunrise * 3600) % 3600);

然后在你希望打上<代码>的时区显示日期。表格:

DateFormat fmt = new SimpleDateFormat();
fmt.setTimeZone(TimeZone.getTimeZone("Europe/Paris")); 
System.out.println(fmt.format(calendar.getTime()));

Answer 3

It seems this is not a java problem, and you found a webservice with a underspecified interface. I googled for a solution and I found several libraries able to calculate sunrise and sunset. For example, this was one of the first results: http://www.jstott.me.uk/jsuntimes/

Answer 4

Float sunriseFloat = new Float(sunrise);  
Float sunsetFloat = new Float(sunset);

    Date startDate = new Date(sunriseFloat.longValue());  
    Date endDate = new Date(sunsetFloat.longValue());
