may help you . I somehow made it work by writing my own library. This is just the instance of code you need to include for changing or converting the date coming from the server side JSON schema.
Code:
code :
cacheElements: function() {
  this.$datePickers = this.$el.find('.datepicker');
  this.$datePickerStart = this.$datePickers.filter('.start');
  this.$datePickerEnd = this.$datePickers.filter('.end');
  this.$loader = this.$el.find('.timeframe-loader');
},

render: function() {
  this.$el.html(this.template(this.model));

  this.cacheElements();

  this.$datePickers.datepicker({ dateFormat: 'dd.mm.yy' });

  this.delegateEvents();

  return this;
},

_onError: function(model, error) {
  this._hideLoader();
  var $where;
  if (error.where == 'startDate') {
    $where = this.$datePickerStart.closest('div');
  } else if (error.where == 'endDate') {
    $where = this.$datePickerEnd.closest('div');
  }
  new Tooltip.View({
    srcElement: $where,
    content: error.message,
    position: 'bottom'
  });
},

_onClickSendData: function() {
  var start = this.$datePickerStart.val();
  var end = this.$datePickerEnd.val();

  var startDate = humanDateStringToJSDateString(start);
  var endDate = humanDateStringToJSDateString(end);

  // If didn't actually change, do nothing:
  var modelStartDate = this.model.get('startDate');
  var modelEndDate = this.model.get('endDate');
  if (this._compareYYYMMDD(new Date(startDate), modelStartDate) !== 0 || this._compareYYYMMDD(new Date(endDate), modelEndDate) !== 0) {
    this._showLoader();

    this.model.set({
      startDate: new Date(startDate),
      endDate: new Date(endDate)
    });
  }
},

_compareYYYMMDD: function(date1, date2) {
  var num1 = dateToString(date1).replace('-','');
  var num2 = dateToString(date2).replace('-','');
  return date1 - date2;
},

_showLoader: function() {
  this.$loader.show();
},

_hideLoader: function() {
  this.$loader.hide();
},

setEndDate: function() {
  this.$datePickerStart.val(dateToDottedString(addDays(new Date(), - App.state.get('timeframe'))));
  this.$datePickerEnd.val(dateToDottedString(new Date()));
}
Is there any existing grok{} pattern for date format YYYY/MM/DD HH:mm:ss?

I wish did fix the issue. No. You find the included patterns on github. The comment to datestamp seems to fit to your YYYY/MM/DD, but DATE_US and DATE_EU are different.
I suggest overload the DATE pattern using grok option patterns_dir and go with DATESTAMP.
code :
DATE_YMD %{YEAR}/%{MONTHNUM}/%{MONTHDAY}
DATE %{DATE_US}|%{DATE_EU}|%{DATE_YMD}

Hope this helps The date you are parsing is not using slashes, but you're defining slashes when you parse it. Switch your slashes to dashes:
code :
var dateObj = str2date(Date_of_joining, "yyyy-mm-dd");
var newDate = date2str(dateObj, "dd/MM/yyyy");

I wish this helpful for you 1/ DOCS: By cusomising the parse and display format with a custom date atapter
In the custom Date Adapter (yours is AppDateAdapter), add a parse method to parse the new date format (DD/MM/YYY) to a date valid date:
code :
   parse(value: any): Date | null {
    if ((typeof value === 'string') && (value.indexOf('/') > -1)) {
      const str = value.split('/');
      const year = Number(str[2]);
      const month = Number(str[1]) - 1;
      const date = Number(str[0]);
      return new Date(year, month, date);
    }
    const timestamp = typeof value === 'number' ? value : Date.parse(value);
    return isNaN(timestamp) ? null : new Date(timestamp);
  }
export class AppDateAdapter extends NativeDateAdapter {
    parse(value: any): Date | null {
        if ((typeof value === 'string') && (value.indexOf('/') > -1)) {
          const str = value.split('/');
          const year = Number(str[2]);
          const month = Number(str[1]) - 1;
          const date = Number(str[0]);
          return new Date(year, month, date);
        }
        const timestamp = typeof value === 'number' ? value : Date.parse(value);
        return isNaN(timestamp) ? null : new Date(timestamp);
      }
   format(date: Date, displayFormat: any): string {
       if (displayFormat == "input") {
           let day = date.getDate();
           let month = date.getMonth() + 1;
           let year = date.getFullYear();
           return this._to2digit(day) + '/' + this._to2digit(month) + '/' + year;
       } else {
           return date.toDateString();
       }
   }

   private _to2digit(n: number) {
       return ('00' + n).slice(-2);
   } 
}

around this issue I can reproduce your results with Apache-Common-Lang-library. It seems the API does not offer any official solution, also not in newest version v3.3.2. Normally a good parser would reject the input 2014-06-06 for the pattern dd-MM-yyyy by throwing an exception but here FastDateFormat tolerates it and cannot even be set to non-lenient mode like SimpleDateFormat.
So the only options left are:
