Notification based on user's time zone

[Sumit32]

Can we trigger a notification based on user's time zone. I want to send an email notification at same time globally.

@Ankur Bawiskar 

For example i want to send email  at 12am in IST, Europe/London, US/Central etc..

Can we achieve through scheduled job.

I have tried these many ways but it is not working. Can you help me on this.

(function calculatedFieldValue(current) {

 var tz = Packages.java.util.TimeZone.getTimeZone('US/Eastern');

var time = new GlideDateTime();
time.setTZ(tz);
 time.setValue(current.sys_created_on);
 return time.getDisplayValue();
 })(current);

.................................................................................................

/ var gr = new GlideRecord("sys_user");
// gr.addEncodedQuery("time_zone=IST");
// gr.query();
// while (gr.next()) {
// gs.info("Timezone Test" + gr.user_name);
// gs.eventQueue("problem_resolve", current, gr.user_name, gr.email);
// }
// var session=gs.getSession();
// var tz=session.getTimeZoneName();
// var time = new GlideTime();
// gs.info(tz);
// gs.info(time);

..................................................................................................................

if (1==1) {
var when = new GlideDateTime();
gs.info("when1 "+ when);
var delay = new GlideTime();
delay.setValue("00:05:00");
when.add(delay);
// gs.info("time is "+delay);
// gs.info("Australia time :"+when);

var gr = new GlideRecord("sys_user");
gr.addEncodedQuery("time_zone=IST");
gr.query();
while (gr.next()){
gs.info("Testing Timezone" + gr.user_name);
gs.eventQueueScheduled("problem_resolve", current, gr.user_name, gr.email, when);
}

This looks quite interesting as well as difficult scenario to implement.

How many such time zones you have? If you have limited time zones like 4-5 then you can write those many scheduled jobs with different time zones to run at 12 AM.
