odata datetimeoffset 过滤器因正时区而失败

Question

我遇到了 odata 过滤问题。我已将我的场景简化为以下内容：我的模型是这样构建的：

public class MyModel
{
    public int ID { get; set; }
    public DateTimeOffset DATE { get; set; }
}

控制器和 GET 实现如下：

public class MyModelController:ODataController
{
    [HttpGet]
    [EnableQuery]
    public IHttpActionResult Get()
    {
        var list = new List<MyModel>();
        list.Add(new MyModel{
            ID = 1,
            DATE = DateTimeOffset.Now.AddDays(-1)
        });
        list.Add(new MyModel {
            ID = 2,
            DATE = DateTimeOffset.Now.AddDays(-2)
        });
        list.Add(new MyModel {
            ID = 3,
            DATE = DateTimeOffset.Now.AddDays(-3)
        });
        
        return Ok(list.AsQueryable());
    }
}

在 DATE 列上执行以下过滤器，结果不错。请注意时区是 negative:

GET https://localhost:44349/odata/MyModel?$filter=DATE le 2020-06-24T15:57:44.3780001-03:00

在 DATE 列上执行以下过滤器会引发异常。请注意，本例中的时区是 positive.

GET https://localhost:44349/odata/MyModel?$filter=DATE le 2020-06-24T15:57:44.3780001+03:00

我是不是漏掉了什么？

同时我发现，+ 在 URL 中有特殊含义。您需要对其进行如下编码：

获取 https://localhost:44349/odata/MyModel?$filter=日期 2020-06-24T15:57:44.3780001%2b03:00

即+ => %2b
