I have a problem in my C# Web API, where an action is return an object with DateTime property. However, when receiving it and converting it to PS object with ConvertFrom-Json the DateTime property is converted to a string.
I then began testing a bit and found it curious how JSON serialize DateTime in Powershell:
`
$object = New-Object psobject -Property @{ DateTime = (Get-Date) }
$object | ConvertTo-Json | ConvertFrom-Json | gm
`
This gives me:
**DateTime NoteProperty System.Management.Automation.PSCustomObject DateTime=@{value=08-03-2016 13:36:27; DisplayHint=2; DateTime=8. marts 2016 14:36:27}**
Too much…
`(Get-Date).Date`
Gives me:
**DateTime NoteProperty datetime DateTime=07-03-2016 23:00:00**
Hurray! datetime property, however this is just the Date…
I thought I would be genius just to do this then:
`(Get-Date).DateTime`
But that gives me a string again…
**DateTime NoteProperty string DateTime=8. marts 2016 14:38:37**
I could ofcourse do this then:
`Get-Date($object | ConvertTo-Json | ConvertFrom-Json).Datetime`
I get what I want:
**TypeName: System.DateTime**
But why oh why?
Any thoughts?
Best regards
Stig

I’d call this a bug in ConvertTo-Json. It should be treating DateTime as a primitive type and not appending any of the extra ETS properties. (The same can be said for any other primitive type that JSON supports, but as far as I know, none of the other ones have extra properties tacked on by PowerShell’s type system).
You can report the bug over on UserVoice: [https://windowsserver.uservoice.com/forums/301869-powershell/category/148044-powershell-engine](https://windowsserver.uservoice.com/forums/301869-powershell/category/148044-powershell-engine)

I guess I don’t understand the value added by creating a new object of an object. Does this get you what you were expecting?
```
$object = Get-Date
```

Bob, no sorry.
I was just trying to simulate getting back a class with a DateTime property - just like from my Web API.
Maybe this is more a C# question?
`
public HttpResponseMessage Testing()
{
Test test = new Test();
test.TestDate = DateTime.Now;
return Request.CreateResponse(HttpStatusCode.OK, test);
}
```
public class Test
{
public DateTime TestDate { get; set; }
}
```
`
In PS:
`
Invoke-RestMethod $url -Method Get | gm
`
What I get return:
``
`
TypeName: System.Management.Automation.PSCustomObject
Name MemberType Definition
`
`Equals Method bool Equals(System.Object obj)
GetHashCode Method int GetHashCode()
GetType Method type GetType()
ToString Method string ToString()
TestDate NoteProperty string TestDate=2016-03-08T19:52:45.2883004+01:00
`
I would have thought that TestDate would be a DateTime and not string…
