下面的代码似乎转换为bst。我在做傻事吗？

        System.out.println(toInterval(DAY_SHIFT, "America/New_York", "UTC"));
    }

    public static final String TIME_FORMAT = "HH:mm";
    public static List<LocalTime> toInterval(String str, String sourceTZ, String destTZ) {
        if (!StringUtils.isBlank(str)){
            final DateTimeFormatter timeFormat = DateTimeFormat.forPattern(TIME_FORMAT).withZone(DateTimeZone.forID(sourceTZ));
            String[] tokens = str.split("-");
            if (tokens!=null && tokens.length==2){

                    long end = timeFormat.parseMillis(tokens[1]);
                    DateTime startTime = new DateTime(start, DateTimeZone.forID(sourceTZ)).toDateTime(DateTimeZone.forID(destTZ));
                    DateTime endTime = new DateTime(end, DateTimeZone.forID(sourceTZ)).toDateTime(DateTimeZone.forID(destTZ));

                            new LocalTime(endTime, DateTimeZone.forID(destTZ)));
                }
                catch (IllegalArgumentException e){
                    e.printStackTrace();
                }

        return null;
    }
}

上面的代码打印出来 [13:00:00.000, 22:15:00.000] . 根据这个链接，应该休息一个小时 [12:00:00.000, 21:15:00.000]
