how to format Knex.js timestamps

I have the next table:

        knex.schema.hasTable('notes').then(function (exists) {
            if (!exists) {
                return knex.schema.createTable('notes', function (t) {
                    t.increments('id').primary();
                    t.string('title', 100).notNullable();
     开发者_开发技巧               t.string('content', 300).notNullable();
                    t.boolean('archived').notNullable().defaultTo(false);
                    t.timestamp('updated_at').defaultTo(knex.fn.now());
                }).then(() => {
                    console.log('* Table created "notes"')
                }).catch((err) => {
                    console.log(err)
                    throw err
                });
            }
        });

It returns the timestamp in this format: YYYY-MM-DDTHH:MM:SS.000Z and i want it in this one: YYYY-MM-DD HH:MM

I tried searching for a solution but didn't find one
