我的日期有问题。也许我在序列化过程中不了解某些内容，但是，例如，我何时将日期时间发送到 Api-Platform (Symfony)
dateEvaluation: "2017-12-05T11:52:00.000Z"
我收到此错误消息
Cannot create an instance of DateTime from serialized data because its constructor requires parameter "time" to be present.
这是我的实体

我不明白为什么缺少“时间”。也许它是用于创建或更新的字段？无论如何，创建和更新的字段使用 ApiPlatform 返回一个带有时区的对象......
created:
{timezone: {name: "Europe/Paris",…}, offset: 561, timestamp: -62169984561}
offset:561
timestamp:-62169984561
timezone:{name: "Europe/Paris",…}
谢谢你的帮助。大卫
