How to sort Date/Time column in angular 4 material sort?

Question

I\'m using angular material table and using matSort for sorting. But it\'s not sorting the dates/time column. It takes the datetime column values as strings.

In addition to the Sagar Kharche's post, if your date is from firebase, I recommended you to do this:

this.dataSource.sortingDataAccessor = (item, property) => {
    console.log(item)
    switch (property) {
      case 'fromDate': {
        return new Date(item.fromDate.seconds * 1000);
      }
      default: return item[property];
    }
  };
