使用Laravel设置Mysql数据库种子时出现奇怪错误

我使用的是Laravel5.6，我在开发时使用了一个数据库播种器来播种我的本地mysql数据库。以下是来自播种机的一些代码：

class DatabaseSeeder extends Seeder
{
    $products = factory(App\Product::class, 100)->create();

    foreach ($products as $product) {
        // Assign some reviews to each product
        $reviews = factory(App\ProductReview::class, rand(0, 10))->make();
        $product->reviews()->saveMany($reviews);
    }
}

播种器大部分时间都按预期工作，但在播种时，我会随机得到一个关于某个列的无效日期时间格式的错误。我不知道是什么原因导致了这种情况，特别是因为问题只出现在播种机运行的20%左右的时间。另外，基于错误，我实际上没有看到datetime格式有任何问题，所以我不确定发生了什么

它似乎也不仅仅局限于评论，其他时候我会在播种者尝试创建产品时看到错误。我将在下面粘贴完整的错误跟踪。希望有人能给我指出正确的方向，看看是什么导致了这一切

这似乎是个奇怪的问题

“日期/时间看起来有效，但实际上是在周日凌晨2点到3点之间，时间从凌晨2点跳到凌晨3点。因此，凌晨2点到3点之间的任何时间都不存在”

将日期/时间转换为正确的时区可以解决此问题

在文件中：

config/app.php

“时区”=>“UTC”//将UTC更改为您的时区，例如：“美国/哈瓦那”

如果您试图在MySQL实例中直接运行该命令，您是收到错误还是工作正常？（顺便问一下，你使用的是哪个MySQL版本？）。谢谢
