Single cron job run on several timezones node-cron

Question

I have configured jobs with node-cron and yeah I love this node module to schedule job in node.

Here I have requirement of sending push notification to users which are located in different timezone.I want to send notification to them on specific time.

Let's say I am sending notification at 9 PM so in all listed timezone cron job will trigger at 9 PM.

var CronJob = require('cron').CronJob;
var job = new CronJob('00 30 11 * * 1-5', function() {
  /*
   * Runs every weekday (Monday through Friday)
   * at 11:30:00 AM. It does not run on Saturday
   * or Sunday.
   */
  }, function () {
    /* This function is executed when the job stops */
  },
  true, /* Start the job right now */
  timeZone /* Time zone of this job. */
);

I know all this and I am doing same for one timezone as mentioned in there doc.

timeZone - [OPTIONAL] - Specify the timezone for the execution. This will modify the actual time relative to your timezone.

But Can I specify multiple timezone here in timezone attribute?

If somebody aware of some other node module can achieve this then let me know?

NOTE : I already know I can configured multiple configuration here for each timezone but what if there are dynamic list.

Answer 1

I don't know of a way to send a list of timezones to the CRON job but you could change the logic in the method that runs inside the cron job.

You could do this :

• run the job every half hour
• if it's a day you want it to run on
• select users where (convert current GMT time to user timezone - if the db can do this) > 11:30 AM in their timezone && hasn't sent a notification yet
• send notifications to the returned users.

You might have already gone this route ... just throwing in my 2c
