I am using the JQuery Ganntt plugin and it needs dates formatted in the Unix epoch format. Using Newtonsoft's Json.Net with these settings 

JsonSerializerSettings microsoftDateFormatSettings = new JsonSerializerSettings
{
    DateFormatHandling = DateFormatHandling.MicrosoftDateFormat
};

return JsonConvert.SerializeObject(headers, microsoftDateFormatSettings);

I get json that looks like the following

[{"desc":"STAT","name":"Status","values":[{"to":"/Date(1357483427000-0500)/","from":"/Date(1354891427000-0500)/","desc":"","label":"Implement","customClass":"ganttBlue","dataObj":{"id":35,"projectId":18705,"updatedById":437996,"updatedByName":"Linda","updated":"/Date(1354891427000-0500)/","statusId":160,"statusDescription":"","status":"Implement"}}]},{"desc":"ASGNTO","name":"Assigned To","values":[{"to":"/Date(1357762454000-0500)/","from":"/Date(1355170454000-0500)/","desc":"Suzy","label":"Suzy","customClass":"ganttRed","dataObj":{"id":55,"projectId":18705,"updatedById":719816,"updatedByName":"Joe","updated":"/Date(1355170454000-0500)/","assignedToId":561260,"assignedToName":"Suzy"}}]}]

The gantt plugin does not like the date with the -500. It wants this, which is generated from using the JavaScriptSerializer

"[{\"desc\":\"STAT\",\"name\":\"Status\",\"values\":[{\"to\":\"\/Date(1357483427000)\/\",\"from\":\"\/Date(1354891427000)\/\",\"description\":\"\",\"label\":\"Implement\",\"customClass\":\"ganttBlue\",\"dataObj\":{\"Id\":35,\"ProjectId\":18705,\"UpdatedById\":437996,\"UpdatedByName\":\"Linda\",\"Updated\":\"\/Date(1354891427000)\/\",\"StatusId\":160,\"StatusDescription\":\"\",\"Status\":\"Implement\"}}]},{\"desc\":\"ASGNTO\",\"name\":\"Assigned To\",\"values\":[{\"to\":\"\/Date(1357762454000)\/\",\"from\":\"\/Date(1355170454000)\/\",\"description\":\"Suzy\",\"label\":\"Suzy\",\"customClass\":\"ganttRed\",\"dataObj\":{\"Id\":55,\"ProjectId\":18705,\"UpdatedById\":719816,\"UpdatedByName\":\"Joe\",\"Updated\":\"\/Date(1355170454000)\/\",\"AssignedToId\":561260,\"AssignedToName\":\"Suzy\"}}]}]"

What would be the proper setting for the Json.Net converter? I want to use Json.net when we move to .net 4.5.

要使其显示类似于 生成的日期JavaScriptSerializer，您必须提供两个设置：

JsonSerializerSettings serializerSettings = new JsonSerializerSettings()
{
    DateFormatHandling = DateFormatHandling.MicrosoftDateFormat,
    DateTimeZoneHandling = DateTimeZoneHandling.Utc
};

使用任何其他类型的DateTimeZoneHandling将导致放入时区偏移量。（似乎Unspecified仍然放入偏移量的错误。）

但是，如果您在整个系统中使用本地时间，那么在序列化日期时，这样做会根据您的时区偏移量来移动日期。你的约会将被取消。

对我来说最简单的解决方法是使用默认的 ISO 日期，设置DateTimeZoneHandling为Local，然后更改客户端以解析 ISO 日期。否则，您需要在序列化之前调整日期或使用您自己的自定义序列化程序。最后两个对我来说似乎都不值得。
