Timezone in EJ2 TypeScript Schedule control

6 Feb 202524 minutes to read

The Scheduler uses the current system time zone by default. If it needs to follow a user-specific time zone, then the timezone property can be used. Apart from the default action of applying a specific timezone to the Scheduler, it is also possible to set different time zone values for each appointment through the properties startTimezone and endTimezone, which can be defined as separate fields within the event fields collection.

Note: timezone property only applicable for the appointment processing and current time indication.

Understanding date manipulation in JavaScript

The new Date() in JavaScript returns the exact current date object with complete time and timezone information. For example, it may return value such as Wed Dec 12 2018 05:23:27 GMT+0530 (India Standard Time) which indicates that the current date is December 12, 2018 and the current time is 5.23 AM on browsers following the IST timezone.

Scheduler with no timezone

When no specific time zone is set to Scheduler, appointments will be displayed based on the client system’s timezone which is the default behavior.

The following code example displays an appointment from 9.00 AM to 10.00 AM when you open the Scheduler from any of the timezone. This is because, we are providing the start and end time enclosing with new Date() which works based on the client browser’s timezone.

import { Schedule, Day, Week, TimelineViews, Month, Agenda } from '@syncfusion/ej2-schedule';

let data: object [] = [{
    Subject: 'Paris',
    StartTime: new Date(2018, 1, 15, 9, 0),
    EndTime: new Date(2018, 1, 15, 10, 0)
}];

Schedule.Inject(Day, Week, TimelineViews, Month, Agenda);

let scheduleObj: Schedule = new Schedule({
    height: '550px',
    selectedDate: new Date(2018, 1, 15),
    views: ['Day', 'Week', 'TimelineWeek', 'Month', 'Agenda'],
    eventSettings: {
        dataSource: data
    }
});
scheduleObj.appendTo('#Schedule');

Scheduler set to specific timezone

When a time zone is set to Scheduler through timezone property, the appointments will be displayed exactly based on the Scheduler timezone regardless of its client timezone. In the following code example, appointments will be displayed based on Eastern Time (UTC -05:00).

import { Schedule, Day, Week, Month } from '@syncfusion/ej2-schedule';
import { scheduleData } from './datasource.ts';

Schedule.Inject(Day, Week, Month);

let scheduleObj: Schedule = new Schedule({
    width: '100%',
    height: '550px',
    views: ['Day', 'Week', 'Month'],
    selectedDate: new Date(2018, 1, 17),
    timezone: 'America/New_York',
    eventSettings: { dataSource: scheduleData }
});
scheduleObj.appendTo('#Schedule');

Display events on same time everywhere with no time difference

Setting timezone to UTC for Scheduler will display the appointments on same time as in the database for all the users in different time zone.

import { Schedule, Day, Week, Month, Timezone } from '@syncfusion/ej2-schedule';
import { fifaEventsData } from './datasource.ts';
import { extend } from '@syncfusion/ej2-base';

Schedule.Inject(Day, Week, Month);

let fifaEvents: Object[] = <Object[]>extend([], fifaEventsData, null, true);
let timezone: Timezone = new Timezone();
for (let fifaEvent of fifaEvents) {
    let event: { [key: string]: Object } = fifaEvent as { [key: string]: Object };
    event.StartTime = timezone.removeLocalOffset(<Date>event.StartTime);
    event.EndTime = timezone.removeLocalOffset(<Date>event.EndTime);
}

let scheduleObj: Schedule = new Schedule({
    width: '100%',
    height: '550px',
    selectedDate: new Date(2018, 5, 17),
    views: ['Day', 'Week', 'Month'],
    timezone: 'UTC',
    eventSettings: { dataSource: fifaEvents }
});

Set specific timezone for events

It is possible to set different timezone for Scheduler events by setting startTimezone and endTimezone properties within the datasource. It allows each appointment to maintain different timezone and displays on Scheduler with appropriate time differences.

import { Schedule, Day, Week, TimelineViews, Month, Agenda } from '@syncfusion/ej2-schedule';

let data: object[] = [{
    Subject: 'Paris',
    StartTime: new Date(2018, 1, 15, 10, 0),
    EndTime: new Date(2018, 1, 15, 12, 30),
    StartTimezone: 'Europe/Moscow',
    EndTimezone: 'Europe/Moscow'
}];

Schedule.Inject(Day, Week, TimelineViews, Month, Agenda);

let scheduleObj: Schedule = new Schedule({
    height: '550px',
    selectedDate: new Date(2018, 1, 15),
    views: ['Day', 'Week', 'TimelineWeek', 'Month', 'Agenda'],
    eventSettings: {
        dataSource: data
    }
});
scheduleObj.appendTo('#Schedule');

Add or remove timezone names to/from the timezone collection

Instead of displaying all the timezone names within the timezone collection (more than 200 are displayed on the editor window timezone fields by default), you can customize the timezone collection at application end as shown in the following example.

import { Schedule, Day, Week, Month, timezoneData } from '@syncfusion/ej2-schedule';
import { scheduleData } from './datasource.ts';

Schedule.Inject(Day, Week, Month);

let customTimezoneData: { [key: string]: Object }[] = [
  { Value: 'America/New_York', Text: '(UTC-05:00) Eastern Time' },
  { Value: 'UTC', Text: 'UTC' },
  { Value: 'Asia/Kolkata', Text: '(UTC+05:30) India Standard Time' }
];

timezoneData.splice(0, timezoneData.length, ...customTimezoneData);

let scheduleObj: Schedule = new Schedule({
  width: '100%',
  height: '550px',
  selectedDate: new Date(2018, 1, 11),
  views: ['Day', 'Week', 'Month'],
  eventSettings: { dataSource: scheduleData }
});
scheduleObj.appendTo('#Schedule');
