I´m trying to store a UNIX timestamp in MongoDB using GraphQL, but it seens that GraphQL has a limit to handle integers. See the mutation below:

const addUser = {

    type: UserType,

    description: 'Add an user',

    args: {

        data: {

            name: 'data',

            type: new GraphQLNonNull(CompanyInputType)

        }

    },

    resolve(root, params) {



        params.data.creationTimestamp = Date.now();



        const model = new UserModel(params.data);

        const saved = model.save();



        if (!saved)

            throw new Error('Error adding user');



        return saved;

    }

}

Result:

  errors: [

    {

      message: Int cannot represent non 32-bit signed integer value: 1499484833027,

      locations: [

        {

          line: 14,

          column: 5

        }

      ],

      path: [

        addUser,

        creationTimestamp

      ]

    }

I´m currently using GraphQLInteger for this field on type definition:

creationTimestamp: { 

    type: GraphQLInt

}

How can I solve that situation if there is no larger GraphQLInt available in GraphQL ?
