You can see the docs here that explains the @Column decorator. In @Column there is an option called type -> here is where you specify which type of date you want to store for that specific column.

More on column types here.

For example (using PostgreSQL):

@Column({ type: 'date' })
date_only: string;

@Column({ type: 'timestamptz' }) // Recommended
date_time_with_timezone: Date;

@Column({ type: 'timestamp' }) // Not recommended
date_time_without_timezone: Date;

Note that date_only is of type string. See this issue for more information.

Hope it helps :)

How about ?

@CreateDateColumn()
created_at: Date;
    
@UpdateDateColumn()
updated_at: Date;

EDIT

You can find more info here

To add more to this ticket as DateTime was not even mentioned:

  /**
   * Start DateTime
   */
  @Column({
    type: 'datetime',
    default: () => 'NOW()',
  })
  @Index()
  start: string;

  /**
   * End DateTime
   */
  @Column({
    type: 'datetime',
    nullable: true,
  })
  @Index()
  end: string;

This is for those not wanting or needing to use

@CreateDateColumn()

@UpdateDateColumn()
