如何将字符串转换'01-01-1970 00:03:44'为datetime？

我坚持一个问题,并希望得到任何帮助.我已经阅读了很多讨论,但它们似乎对我不起作用.

//I have a date as a string which I want to get to a date format of dd/MM/yyyy
var collectionDate = '2002-04-26T09:00:00'; 

//used angularjs date filter to format the date to dd/MM/yyyy
collectionDate = $filter('date')(collectionDate, 'dd/MM/yyyy'); //This outputs 26/04/2002 as a string

如何将其转换为日期对象？我想这样做的原因是因为我想在谷歌图表指令中使用它,其中一列必须是日期.我不希望列类型为字符串:

例如:

var data = new google.visualization.DataTable();
                    data.addColumn('date', 'Dates');
                    data.addColumn('number', 'Upper Normal');
                    data.addColumn('number', 'Result');
                    data.addColumn('number', 'Lower Normal');
                    data.addRows(scope.rows);.................

我需要将发布数据发送到API服务器。我有一个表单，它有一个日期选择器字段。现在，如果我将数据发送到服务器，它将发送格式化为服务器拒绝的日期。

这是发送的整个数据的表示形式：

{
  address: "Address",
  department: 1,
  dob: "1997-08-19T18:00:00.000Z",
  email: "chitholian@gmail.com",
  gender: "male",
  hall: 1,
  id: 16701016,
  name: "Atikur Rahman Chitholian",
  phone: "No phone number",
  religion: "islam",
  semester: 1,
  session: "2015 - 2016"
}

这是组件的代码：

import {Component, OnInit} from '@angular/core';
import {FormBuilder, FormGroup, Validators} from '@angular/forms';
import {Department, Hall, Semester, Student} from '../custom/interfaces';
import {DepartmentService} from '../services/department.service';
import {MatSnackBar} from '@angular/material';
import {StudentService} from '../services/student.service';
import {Router} from '@angular/router';
import {DatePipe} from '@angular/common';

@Component({
  selector: 'app-student-reg',
  template: `
    <form class="panel" …
