Display in ion-datetime a suggested value

Hello,

I have the following need: the end-user should input a datetime in a field that is empty. Thanks to the business logic, this datetime can be suggested by the app. So what I would like to do is that clicking on the empty field displays the suggested datetime in both the field and the ion-datetime component.

Here is my code:

In HTML

			<ion-datetime 	displayFormat='YYYY-MM-DD HH:mm' 
							pickerFormat='YYYY-MM-DD HH:mm'
							text-center 
							(click)="init_worked_time()" 
							[(ngModel)]='worked_time'>					
			</ion-datetime>

In Typescript

	init_worked_time() {
		if (this.worked_time == undefined) {
			if (this.times.start_time != 0) { 
				let tzoffset = (new Date()).getTimezoneOffset() * 60000;
				this.worked_time = moment(this.times.start_time).subtract(tzoffset, 'milliseconds').toISOString().slice(0, -1);
			} 
		}
	}

The problem is that the suggested value is well displayed in the field after clicking on it but the ion-datetime component shows the current UTC time (even not local timeā€¦)

Is there any better approach for such need? Or maybe is there any possibility to update programmatically the displayed value of the ion-datetime component?

Thanks!
