postgresql json date format issue

Question

I am having issues with my postgresql dates. I a column with type date. An example value in the column is 2016-01-28. However, when I make an AJAX request to retrieve data from the server, the date is returned as "2016-01-28T07:18:01.000Z". Does anyone know why the additional T07:18:01.000Z is there and how I can prevent it?

The only workaround I know is to use the dateformat package (https://www.npmjs.com/package/dateformat) to parse the date once it is returned from the AJAX request - but i'd rather not do it if I can return the date without the additional T07:18:01.000Z.

Here is my query:

knex('reports')
.where({
    projectid: req.params.id
})
.then(function(data) {
    console.log(data)
    console.log(data[0].start_date //returns "2016-01-28T07:18:01.000Z"
    res.send(data)
});

Thanks in advance!
