powershell - How do I correctly serialize a PSObject with a DateTime into JSON? -

lets have psobject integer , date want serialize json , have recipients able deserialize it. in javascript following json:

json.stringify({date: new date(), number: 23}) "{"date":"2014-09-10t14:11:27.092z","number":23}"  json.parse(json.stringify({date: new date(), number: 23})) >> object {date: "2014-09-10t14:13:28.950z", number: 23} 

that looks pretty standard json can interpreted correctly javascript.

however, appears powershell's convertto-json inconsistent datetime serialization can't convert , forth correctly. illustrate this:

ps c:\dev> $testobj = new-object -typename psobject -property @{ date = get-date; number = 23; } ps c:\dev> $testobj  number date ------ ----     23 9/10/2014 9:52:14  ps c:\dev\git\strawman> $testobj | convertto-json {     "number":  23,     "date":  {                  "value":  "\/date(1410357134361)\/",                  "displayhint":  2,                  "datetime":  "wednesday, september 10, 2014 9:52:14 am"              } }  ps c:\dev> $testobj | convertto-json | convertfrom-json  number date ------ ----     23 @{value=9/10/2014 1:52:14 pm; displayhint=2; datetime=wednesday, september 10, 2014 9:52:14 am} 

not json produces date property not valid @ , can't interpreted correctly javascript, powershell's convertfrom-json can't interpret correctly give same looking object back.

is there way correctly serialize psobject datetime valid json can correctly deserialized recipients?

i ended writing function convert psobject psobject can converted cleaner json:

<# .synopsis     creates new psobject properties of original object not able     serialized json converted value can converted json.      includes following types:     *   datetime      conducts deep property search .example      convert custom psobject have parsable dates in json      $customobject = new-object -typename psobject -property @{ date = get-date; number = 23; innerdate = new-object -typename psobject -property @{date=get-date;} }      ## bad json     ps c:\dev> $customobject | convertto-json     {         "date":  {                      "value":  "\/date(1410372629047)\/",                      "displayhint":  2,                      "datetime":  "wednesday, september 10, 2014 2:10:29 pm"                  },         "number":  23,         "innerdate":  {                           "date":  {                                        "value":  "\/date(1410372629047)\/",                                        "displayhint":  2,                                        "datetime":  "wednesday, september 10, 2014 2:10:29 pm"                                    }                       }     }      ## json     ps c:\dev> $customobject | convertto-jsonifiablepsobject | convertto-json     {         "date":  "2014-09-10t14:10:29.0477785-04:00",         "number":  23,         "innerdate":  {                           "date":  "2014-09-10t14:10:29.0477785-04:00"                       }     }  #> function convertto-jsonifiablepsobject {     param     (         [parameter(mandatory=$true, valuefrompipeline=$true)]         [psobject]$object     )      $newobjectproperties = @{}      foreach ($property in $object.psobject.properties)     {         $value = $property.value          if ($property.typenameofvalue -eq "system.management.automation.pscustomobject")         {             $value = convertto-jsonifiablepsobject -object $property.value         }         elseif ($property.typenameofvalue -eq "system.datetime")         {             $value = $property.value.tostring("yyyy'-'mm'-'dd't'hh':'mm':'ss.fffffffk")         }          $newobjectproperties[$property.name] = $value     }      return new-object -typename psobject -property $newobjectproperties }
