DateTimeOffset loosing Timezone info

[oliverjanik]

Here's the test that fails:

[Fact]
public void JTokenDateTest()
{
    var json = JToken.Parse(@"{ ""lastModifiedAt"": ""2015-04-30T23:59:02.465+12:00"" }");

    Assert.Equal("2015-04-30T23:59:02.465+12:00", json.Value<string>("lastModifiedAt"));

    var dto = (DateTimeOffset)json["lastModifiedAt"];

    Assert.Equal(12, dto.Offset.Hours);
} 

This fails both asserts. The question is WTF? Why does the parser even try to interpret the time information when it's actually a JSON string? I thought I was going crazy. The only interpretation should happen when I cast it to the DateTimeOffset.

JToken.Parse reads dates as DateTime by default. Look at the DateParseHandling setting.

What about the wrong timezone info? Do you not consider this an issue? Why does it modify the offset in a round-trip conversion?

[JamesNK]

DateTime doesn't preserve the timezone.

IMHO, I think it's a crazy default. Especially considering DateTime is such a bad fit for ISO8601.
