我想转换ms-since-1970-timestamp为带有时区的日期(德国).

这里有两个代码变体 - 至少,我记得使用它并且它有效:

import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
import java.util.GregorianCalendar;
import java.util.Locale;
import java.util.TimeZone;

public class TestDate {

    public static void main(String[] args) {
        Calendar cal = GregorianCalendar.getInstance(TimeZone.getTimeZone("Germany"), Locale.GERMANY);

        Date d = new Date();
        cal.setTime(d);

        System.out.println(String.format("%02d.%02d.%04d %02d:%02d:%02d", 
                cal.get(Calendar.DAY_OF_MONTH), cal.get(Calendar.MONTH)+1, cal.get(Calendar.YEAR),
                cal.get(Calendar.HOUR_OF_DAY),  cal.get(Calendar.MINUTE),  cal.get(Calendar.SECOND)));

        SimpleDateFormat df = new SimpleDateFormat( "dd.MM.yyyy HH:mm:ss.S" );
        df.setTimeZone(TimeZone.getTimeZone("Germany"));
        System.out.println(df.format(d));
    }

}

这真的很奇怪,因为我找不到2小时时差的原因.

它应该是:16:05:20 代码打印:14:05:20两种变体.

有人可以帮帮我,告诉我这里出了什么问题吗？

可能重复:
尝试设置char数组的字符时程序崩溃

我有一个示例代码,按预期工作:

/* strtok example */
#include <stdio.h>
#include <string.h>

int main ()
{
  char str[] ="- This, a sample string.";
  char * pch;
  printf ("Splitting string \"%s\" into tokens:\n",str);
  pch = strtok (str," ,.-");
/*
  while (pch != NULL)
  {
    printf ("%s\n",pch);
    pch = strtok (NULL, " ,.-");
  }
*/
  return 0;
}

...除非我将char str []更改为char*str,它不应该在语义上产生任何差异:

/* strtok example */
#include <stdio.h>
#include <string.h>

int main ()
{
  char * str ="- This, a sample string.";
  char * …
