Start ion-datetime picker with my LOCAL time

I have this:

<ion-datetime formControlName="hourStart" (ionChange)="setHour($event, 'start')" displayFormat="HH:mm" pickerFormat="HH:mm" placeholder="hh:mm"></ion-datetime>

If I tap on datetime control it shows the picker with UTC time.

If I use

<ion-datetime formControlName="hourStart" [(ngModel)]="myDate" (ionChange)="setHour($event, 'start')" displayFormat="+HH:mm" pickerFormat="HH:mm" placeholder="hh:mm"></ion-datetime>

with myDate= new Date()

The ion datetime starts with this time, It is possible to configure the picker without show it on control? Only when the picker is present.

thanks

Someone can help me with this?
