Jodatime:由于时区偏移转换导致的非法瞬间(夏令时 'gap')

Jodatime: Illegal instant due to time zone offset transition (daylight savings time 'gap')

这次崩溃发生在 2 天前,我不明白为什么。一切都完美运行了 1 年:

Fatal Exception: org.joda.time.IllegalFieldValueException Value 2 for hourOfDay is not supported: Illegal instant due to time zone offset transition (daylight savings time 'gap'): 2019-03-31T02:09:00.000 (Europe/Paris)

我的代码:

DateTime dtToRefresh = mDateTime != null ? mDateTime : DateTime.now();
                        dtToRefresh = dtToRefresh.secondOfMinute().setCopy(0);
                        dtToRefresh = dtToRefresh.millisOfSecond().setCopy(0);
                        dtToRefresh = dtToRefresh.hourOfDay().setCopy(hourOfDay);
                        dtToRefresh = dtToRefresh.minuteOfHour().setCopy(minute);

崩溃开始于:

dtToRefresh = dtToRefresh.hourOfDay().setCopy(hourOfDay);

"hourOfDay" 距离日期时间选择器(经典过程)一小时。

你有什么调查方法吗?

非常感谢!

巴黎夏令时从 3 月 31 日开始,因此从那天起您的代码就会崩溃。所以你没有实现你的代码来支持夏令时。

如果您手动计时意味着您需要为该时区实施 DST 时间。如果它占用系统时间就没问题。

解决方案:

捕获异常并尝试增加 1 小时或减少 1 小时。

 try 
 {
   DateTime dtToRefresh = mDateTime != null ? mDateTime : DateTime.now();
                    dtToRefresh = dtToRefresh.secondOfMinute().setCopy(0);
                    dtToRefresh = dtToRefresh.millisOfSecond().setCopy(0);
                    dtToRefresh = dtToRefresh.hourOfDay().setCopy(hourOfDay);
                    dtToRefresh = dtToRefresh.minuteOfHour().setCopy(minute);
 } 
 catch (IllegalArgumentException iae) 
 { 
    dttoRefresh.plusHours(1);
 }
