我正在将时间从 CST 转换为本地时间,但 getTimeZone
似乎无法正常工作。
String cstTime = "2013-06-21 14:00:00";
SimpleDateFormat simpleDateFormat = new SimpleDateFormat(
"yyyy-MM-dd HH:mm:ss");
simpleDateFormat.setTimeZone(TimeZone.getTimeZone("CST"));
Date date = null;
try {
date = simpleDateFormat.parse(cstTime);
} catch (ParseException e) {
System.out.println("Parse time error");
e.printStackTrace();
}
TimeZone destTz = TimeZone.getDefault();//here I should get EDT on my phone
simpleDateFormat.setTimeZone(destTz);
String convertedLocalTime = simpleDateFormat.format(date);
//the converted time I get is "2013-06-21 10:00:00"
//but it should be "2013-06-21 15:00:00"
它似乎使用的是 GMT 而不是 CST,下面是我在调试时得到的结果:
String abc = TimeZone.getTimeZone("CST").toString();
System.out.println("CST:"+abc);
Output:
I/System.out(19404): CST:java.util.SimpleTimeZone[id=GMT,offset=0,dstSavings=3600000,
useDaylight=false,startYear=0,startMode=0,startMonth=0,startDay=0,startDayOfWeek=0,
startTime=0,endMode=0,endMonth=0,endDay=0,endDayOfWeek=0,endTime=0]
是否使用 GMT?为什么.. 提前致谢!
编辑:
终于可以用了
simpleDateFormat.setTimeZone(TimeZone.getTimeZone( "GMT-5")); //GMT-5 is for CDT, I found my server is actually using CDT not CST
仍然不知道为什么使用字符串“CST”不起作用...
最佳答案
来自 getTimeZone 的 javadoc:
Returns a TimeZone corresponding to the given id, or GMT for unknown ids.
An ID can be an Olson name of the form Area/Location, such as America/Los_Angeles.
The getAvailableIDs() method returns the supported names.
尝试使用 getAvailableIDs?
关于java - TimeZone.getTimeZone ("CST") 返回 GMT,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/17242764/
