格林尼治时间转化详解：
首先 Mon Dec 09 22:06:24 格林尼治标准时间+0800 2013 字段一个格林尼治标准时间时间，一般情况下字段中不会含有中文，对于这种格式有两种解决方法
1剔除中文字符串
public static String convertGMTToLoacale(String gmt){
String cc = gmt.substring(0, 19) + gmt.substring(33, 38);
SimpleDateFormat sdf = new SimpleDateFormat("EEE MMM dd HH:mm:ss yyyy",new Locale("English"));
try {
Date date = sdf.parse(cc);
SimpleDateFormat dateformat = new SimpleDateFormat("dd/MM");
String result = dateformat.format(date);
return result;
} catch (ParseException e) {
}
return "";
}
2.第二种方法是在不进行字符串剔除的情况下：
在simpleDateFormat方法中将格式字符串变换为："EEE MMM dd HH:mm:ss 格林尼治标准时间+0800 yyyy" 就可以了。这样就可一将时间转换为Date类型：
private DateFormat format = new SimpleDateFormat("EEE MMM dd HH:mm:ss 格林尼治标准时间+0800 yyyy",Locale.ENGLISH);
3.第三种方法:
String str = "Wed Jun 5 00:00:00 GMT+08:00 2013";//在08与00之间加：
java.text.SimpleDateFormat sdf = new SimpleDateFormat("E MMM dd HH:mm:ss z yyyy",Locale.US);
System.out.println(sdf.format(new Date()));
Date d;
try {
d = sdf.parse(str);
sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
System.out.println(sdf.format(d));
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
4.第四种方法:
long d2 = Date.parse("Fri Aug 15 08:00:37 CST 2014");
Date datetime=new Date(d2);
System.out.println(datetime.toLocaleString());
