DateTime value is different across different versi

问题:

I have a service(Language: VB.NET, Framework:.NET 3.5) that returns a dataset from which I read a date. The value of the column in the database is: "1980-03-30 00:00:00.000".

In a client(Language: C#) that uses .NET 3.5, the value is coming thorough as : 3/30/1980 12:00:00 AM

However, when I change the same client to use .NET 4 or .NET 4.5, the date which comes through the service is: 3/29/1980 11:00:00 PM

The difference in DateTime values is not because of .Net framework, its because of the locale settings.

Never pass DateTime values through your web service, pass DateTimeOffset and then convert to DateTime type in your client.
