让我们考虑以下代码:
SimpleDateFormat sdf = new SimpleDateFormat("HH:mm:ss dd/MM/yyyy", Locale.US);
long start = sdf.parse("10:30:00 30/09/2009").getTime();
long end = sdf.parse("10:30:00 30/10/2009").getTime();
Calendar c = Calendar.getInstance(Locale.US);
c.setTimeInMillis(start);
System.out.println("Start = " + c.getTime());
c.setTimeInMillis(end);
System.out.println(" End = " + c.getTime());
运行此代码段时,我有以下输出:
When running this code snippet, I have the following output:
Start = Wed Sep 30 10:30:00 CEST 2009
End = Fri Oct 30 10:30:00 CET 2009
为什么我得到不同的时区?
Why do I get different timezone ?
请注意,如果我将第一个日期设置为 8 月,第二个日期设置为 9 月,则两种情况下的输出将显示相同的时区:
Note that if I set the first date in august and the second one in september, the output will display the same timezone in both cases:
long start = sdf.parse("10:30:00 30/08/2009").getTime();
long end = sdf.parse("10:30:00 30/09/2009").getTime();
将显示:
Start = Sun Aug 30 10:30:00 CEST 2009
End = Wed Sep 30 10:30:00 CEST 2009
我使用的是 Java 1.6.0_14

CEST
