推荐答案
客户已提交无效的时间（因为DST转换时间） 并且服务器刚刚响应，告诉您。客户端是否设置为自动调整夏令时？服务器完成了验证
的工作时间，确保您提交有效的日期时间，以确保您提交有效的日期时间。
The client has submitted an invalid time (because of the DST transition time) and the server has just responded to that to tell you so. Was the client set to automatically adjust time for daylight savings ?. The server has done it job in validating the datetime it's really up to the client to ensure your submitting a valid datetime.
