我正在将时间从CST转换为当地时间,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"
它似乎是使用GMT而不是CST,以下是我在调试时得到的:
- 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]
它是否使用GMT?为什么..
提前致谢!
编辑:
终于通过使用它得到了它
- 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”无法正常工作…
解决方法
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?
