DateTime format in DataService

Hey folks,

   I have been trying to create a record using the DataService as specified here: https://academy.bpmonline.com/documents/technic-sdk/7-8/dataservice-add…

I have a DateTime column in the object I am trying to add, but in the documentation there is nothing saying regarding the format with which I should send the DateTime value to the service. I tried a lot of different known formats (yyyy-MM-dd HH:mm:ss, yyyy-MM-ddTHH:mm:ss, yyyy-MM-dd HH:mm, dd/MM/yyyy HH:mm:ss, yyyy-MM-ddTHH:mm:ss, and so on) but I always get the error message from server:

 {"success":false,"responseStatus":{"ErrorCode":"FormatException","Message":"Input string was not in a correct format.","Errors":[]},"rowsAffected":-1,"nextPrcElReady":false}

The json I am sending is as follows, currently using the format yyyy-MM-ddTHH:mm

{"RootSchemaName":"UsrStudents","ColumnValues":{"Items":{"UsrName":{"ExpressionType":2,"Parameter":{"DataValueType":1,"Value":"Suporte"}},"UsrEmail":{"ExpressionType":2,"Parameter":{"DataValueType":1,"Value":"suporte@vedantaonline.org"}},"UsrFederalInscriptionId":{"ExpressionType":2,"Parameter":{"DataValueType":1,"Value":null}},"UsrAddressLine1":{"ExpressionType":2,"Parameter":{"DataValueType":1,"Value":null}},"UsrAddressLine2":{"ExpressionType":2,"Parameter":{"DataValueType":1,"Value":null}},"UsrAddressCity":{"ExpressionType":2,"Parameter":{"DataValueType":1,"Value":null}},"UsrAddressCountry":{"ExpressionType":2,"Parameter":{"DataValueType":1,"Value":null}},"UsrAddressZipcode":{"ExpressionType":2,"Parameter":{"DataValueType":1,"Value":null}},"UsrPhone":{"ExpressionType":2,"Parameter":{"DataValueType":1,"Value":null}},"UsrCreationTimestamp":{"ExpressionType":2,"Parameter":{"DataValueType":7,"Value":"2016-03-11T11:01"}}}},"Filters":{"FilterType":6,"Items":{"FilterById":{"FilterType":1,"ComparisonType":3,"LeftExpression":{"ExpressionType":0,"Parameter":null,"ColumnPath":"Id"},"RightExpression":{"ExpressionType":2,"Parameter":{"DataValueType":1,"Value":"67b36b17-72ae-4bab-bdd3-eb3159f9150d"},"ColumnPath":null}}}}}

The problem happens when I try to set this field: "UsrCreationTimestamp":{"ExpressionType":2,"Parameter":{"DataValueType":7,"Value":"2016-03-11T11:01"}} which is DateTime

Best regards
