I\'ve seen so many different standards for the JSON date format:
\"\\\"\\\\/Date(1335205592410)\\\\/\\\"\" .NET JavaScriptSerializer \"\\\"\\\\/Date(
it is work for me with parse Server
{ "ContractID": "203-17-DC0101-00003-10011", "Supplier":"Sample Co., Ltd", "Value":12345.80, "Curency":"USD", "StartDate": { "__type": "Date", "iso": "2017-08-22T06:11:00.000Z" } }
