TimeZone.getDefault（）的结果

sun.util.calendar.ZoneInfo [id =“ Europe / Belgrade”，offset = 3600000，dstSavings = 3600000，useDaylight = true，transitions = 119，lastRule = java.util.SimpleTimeZone [id = Europe / Belgrade，offset = 3600000，dstSavings = 3600000，useDaylight = true，startYear = 0，startMode = 2，startMonth = 2，startDay = -1，startDayOfWeek = 1，startTime = 3600000，startTimeMode = 2，endMode = 2，endMonth = 9，endDay = -1，endDayOfWeek = 1，endTime = 3600000，endTimeMode = 2]]

DateTimeZone.getDefault（）的结果

UTC

问题描述

为PrecalculatedZone选择的偏移量不正确。 iTransitions包含错误的值（针对以下测试用例）

iTransitions = {long[3]@751} 0 = -9223372036854775808 1 = 947030400000 (2000-01-05T00:00:00.000Z) 2 = 947196000000 (2000-01-06T22:00:00.000Z) <-22:00而不是00:00

originalDateTimeZone是UTC。

public void testPrecalculatedZoneOffsets() throws IOException {
DateTime minimumDate = new DateTime(1, 1, 1, 0, 0, 0, originalDateTimeZone);

DateTime firstDate = new DateTime(2000, 1, 5, 0, 0, 0, originalDateTimeZone);
DateTime secondDate = firstDate.plusDays(2);
int OFFSET = 120 * MILLIS_PER_MINUTE;
DateTimeZoneBuilder builder = new DateTimeZoneBuilder()
        .setStandardOffset(0)
        .addRecurringSavings("Offset initializing DST rule " + minimumDate.toString(), 0,
                minimumDate.getYear(), minimumDate.getYear(), 'w', 1, 1, 0, false, minimumDate.getMillisOfDay())
        .addCutover(firstDate.getYear(), 'w', firstDate.getMonthOfYear(), firstDate.getDayOfMonth(), 0, false, firstDate.getMillisOfDay())
        .setStandardOffset(OFFSET)
        .addRecurringSavings("Offset initializing DST rule " + firstDate.toString(),
                0, firstDate.getYear(),
                firstDate.getYear(), 'w', firstDate.getMonthOfYear(),
                firstDate.getDayOfMonth(), 0, false, 0)
        .addCutover(secondDate.getYear(), 'w', secondDate.getMonthOfYear(), secondDate.getDayOfMonth(), 0, false, secondDate.getMillisOfDay())
        .setStandardOffset(0)
        .addRecurringSavings("Offset initializing DST rule " + secondDate.toString(),
                0, secondDate.getYear(),
                secondDate.getYear(), 'w', secondDate.getMonthOfYear(),
                secondDate.getDayOfMonth(), 0, false, 0);

DateTimeZone dateTimeZone = builder.toDateTimeZone("ID", false);

//Failing assertion
assertEquals(OFFSET, dateTimeZone.getOffset(secondDate.minusMinutes(1)));

assertEquals(OFFSET, dateTimeZone.getOffset(secondDate.minusDays(1)));
assertEquals(0, dateTimeZone.getOffset(secondDate.plusDays(1)));}

测试用例或iTransitions计算是否有问题？

PrecalculatedZone-iTransitions包含不正确的值
