Json Date Serialization Timezone

Posted on

This one tripped me this week - although the MSDN doc for MinValue and MaxValue will tell you 'UTC', they aren't truly that. They are declared as kind 'unspecified' rather than UTC, which will lead to somewhat unexpected results in Json serialization. If like us you enable internally the DateTimeStyles.AdjustToUniversal of Newtonsoft.Json.Converters' IsoDateTimeConverter, during Json serialization DateTime::ToUniversalTime() will be called. As the kind is unspecified 'The current DateTime object is assumed to be a local time, and the conversion is performed as if Kind were Local.' Oops. Here in Seattle's PST, 0001-01-01T00:00:00.0000000Z suddenly became 0001-01-01T08:00:00.0000000Z, etc.

In Sharepoint 2013, getting data in JSON there is no format to convert date into date only format, because in that date should be in ISO format yourDate.substring(0,10) This may be helpful for you. JSON Serialization Options 1. Set the Json serializations options in the Startup.cs file. This changes the serialization so that property name case isn't modified from whats on the server side. Public void ConfigureServices(IServiceCollection services) { // Add framework services. The DateTime serialization format in the built-in JSON serializer in.NET is particularly inconvenient as it requires a regular expression to parse and is not human-readable which makes debugging a pain. JSON doesn’t have a standard Date format per say. Instead, serialize the date to string, and pass the string back and forth, creating a Javascript function to create a new date on the client based on the formatted string. Obviously, this can get a little hairy.

So, just like you should use DateTime.UtcNow over DateTime.Now, you should also use newDateTime(0L, DateTimeKind.Utc) over DateTime.MinValue and use newDateTime(3155378975999999999L, DateTimeKind.Utc) over DateTime.MaxValue to avoid surprises going over the wire between clients and servers distributed around the world.
