Sequelize convert date from UTC to local

Question

I have a problem with queries in sequelize.js.

In database I store model with myDate field which is stored in UTC. I also have a query where time period is specified:

AND p.myDate BETWEEN :dateStart AND :dateEnd

Using sequelize.query , I replace parameters with:

• dateStart: 2018-09-11T22:00:00.000Z
• dateEnd: 2018-09-14T14:15:40.609Z

and now the problem is that I see query is executing however with localTime values:

AND p.myDate BETWEEN '2018-09-12 00:00:00' AND '2018-09-14 16:15:40'

Why did it convert it to the local time? I was not able to find the right answer.

Answer 1

You can specify the time zone in which you want to read/write in the config of Sequelize like this.

development: {
    username: 'postgres',
    password: 'postgres',
    database: 'your_database_name',
    host: '127.0.0.1',
    port: 5432,
    dialect: 'postgres',
    dialectOptions: {
      useUTC: false, // for reading from database
    },
    timezone: '+05:30', // for writing to database
  },
