JSON Date Format

Hi,

We have a Gateway service with some date fields (ABAP datatype DATS converted to Edm.DateTime or Edm.DateTimeOffset).

When service is called with output format JSON, date values are represented in MicrosoftDateFormat format (e.g. "/Date(1448841600000)/").

In contrary, when output format is XML, dates are in ISO-8601 format: YYYY-MM-DDThh:mm:ssTZD (e.g. 1997-07-16T19:20:30+01:00).

Is there any way to change the JSON date format, either in field level or system level?
