You can use setHours, setMinutes and setSeconds method of date object. PrimeNg p-calendar uses the date object.

Here it is. component.ts

import { Component } from '@angular/core';
import { FormBuilder } from '@angular/forms';

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})
export class AppComponent  {
  date1 = new Date();
  date2 = new Date();
  constructor(){
    this.date1.setHours(0);
    this.date1.setMinutes(0);
    this.date1.setSeconds(0);
    this.date2.setHours(0);
    this.date2.setMinutes(0);
    this.date2.setSeconds(0);
  }
}

Component.html

<div class="ui-g-12 ui-md-4">
        <h3>Start Time</h3>
        <p-calendar [(ngModel)]="date1" [showTime]="true" hourFormat="24"></p-calendar>
    </div>
<br>

<div class="ui-g-12 ui-md-4">
        <h3>End Time</h3>
        <p-calendar [(ngModel)]="date2" [showTime]="true" hourFormat="24"></p-calendar>
</div>

working code

Here's an example of handling a prime range picker calendar with moment.

onRangeDateFilterApply(): void {
        if (this.rangeDateFilterValue[0] && this.rangeDateFilterValue[1]) {

            const timezoneOffset = moment(this.rangeDateFilterValue[0]).utcOffset();

            this.dateFilter = {
                dateRange: { from: moment(this.rangeDateFilterValue[0]).utc().add(timezoneOffset, 'minutes').startOf('day').format(), to: moment(this.rangeDateFilterValue[1]).utc().add(timezoneOffset, 'minutes').endOf('day').format()}
            }
            // do stuff
        }
}
