How to configure actual day on date-time

Hello, im new on this and i have a problem trying to show current day on datetime imput:

html file:

<ion-datetime
        presentation="date"
        [multiple]="true"
        display-format="YYYY MMMM DD"
        [(ngModel)]="newCron.fechas"
      ></ion-datetime>

TS:

 newCron: any = {
    id_sector:'',
    fechas:[],
  }

if i delete: [(ngModel)]=“newCron.fechas”
the calendar show actual day by default, but if don’t delete that, the calendar show by default an older date.

How can i solve this?

Thanks for your time!

I find the solution:

fechas:[] = new Date().toISOString()

Ciao!

//////// NEW PROBLEM

Now just the first date have a different format:

1. fechas: Array(3)

  1. 0: "2022-12-03T03:58:00-03:00"
  2. 1: "2022-12-08"
  3. 2: "2022-12-09"

I don’t understand.
