Convert DateTime from one time zone to another in scoped App and Global

[mahesh009]

how can we convert a time from one timezone to another timezone in both scoped applications and global?

[mahesh009 · Accepted solution]

function convertDateTimeInGlobal(dateTimeStr, fromTimeZone, toTimeZone) {

    var gDate = new GlideDateTime();

    gDate.setTimeZone(fromTimeZone);

    gDate.setDisplayValue(dateTimeStr);

    gDate.setTimeZone(toTimeZone);

    return String(gDate.getDisplayValue());

}

gs.print(convertDateTimeInGlobal("2025-09-16 12:00:00", "GMT", "IST"));

function convertDateTimeInScopedAPP(dateTimeStr, fromTimeZone, toTimeZone) {

    var scheduleDateinfrTZ = new GlideScheduleDateTime("TZID=" + fromTimeZone + ";" + dateTimeStr);

    var dateTimeInternal = scheduleDateinfrTZ;

    var schedDateintoTz = new GlideScheduleDateTime(dateTimeInternal);

    schedDateintoTz.setTimeZone(toTimeZone);

    /* Return the converted date-time as a string */

    return String(schedDateintoTz);

}

gs.info(convertDateTimeInScopedAPP("2025-09-16 12:00:00", "GMT", "IST"));

@mahesh009 

this will work in both

var now = new GlideDateTime();
gs.info("System Time is " + now);
var gsdt = new GlideScheduleDateTime(now);
gsdt.setTimeZone("Europe/London");
gs.info("London time is " + gsdt.getGlideDateTime().getDisplayValue());

Global Output

Scoped Output

While this solution converts time from the system's local time zone to another, my approach offers greater flexibility by enabling conversions between any two time zones, regardless of the system timezone
