PowerShell and DateTime

i create type:

          $authticketrepresentationsource = @"  using system;    namespace sonicfoundry.mediasite.webapi.model  {      public class authorizationticketrepresentation`      {`          public string ticketid { get; set; }          public string username { get; set; }          public string clientipaddress { get; set; }          public string owner { get; set; }          public datetime creationtime { get; set; }          public datetime expirationtime { get; set; }          public string resourceid { get; set; }          public int minutestolive { get; set; }      }  }  "@            add-type -typedefinition $authticketrepresentationsource  

i create instance , populate ad convert json string:

        $poststr = [system.text.encoding]::utf8.getbytes($jsonauthticketrepresentation.tostring())

then post data url. problem dates come out as:

{
    "ticketid":  "00000000-0000-0000-0000-000000000000",
    "username":  "kevinb",
    "clientipaddress":  "10.0.70.154",
    "owner":  "",
    "creationtime":  "\/date(1379610208888)\/",
    "expirationtime":  "\/date(-62135575200000)\/",
    "resourceid":  "773820afc2004c8dad7b8c023201dec218",
    "minutestolive":  5
}

rather than

{  "ticketid":"00000000-0000-0000-0000-000000000000",  "username":"kevinb",  "clientipaddress":"10.0.70.154",  "owner":"",  "creationtime":"2013-09-19t12:34:22.0987775-05:00",  "expirationtime":"0001-01-01t00:00:00",  "resourceid":"599bc68366fd407a81c004e9ca91147a1d",  "minutestolive":5  }

this causing deserialization issues server data being posted to. how can latter serialized representation of dates?

thank you.

hi kevin,

this default serialization dates in json represents milliseconds since beginning of unix epoch. 

(new-object datetime (1970,1,1)).addmilliseconds(1379610208888)

the workaround use string property or call properties tostring method before converting json:

$test = new-object sonicfoundry.mediasite.webapi.model.authorizationticketrepresentation $test.creationtime=get-date $test.expirationtime=$test.creationtime.adddays(5) #modify according stringformat you'd $test | select @{n="creationtime";e={$_.creationtime.tostring("s")}},@{n="expirationtime";e={$_.expirationtime.tostring("s")}} | convertto-json
