Time conversion between different timezones in scoped application

[Anjali Priya]

I have a requirement where I need to write a script to convert CET timezone to a dynamic (user input) timezone value, in a scoped application. I have tried using setTimeZone() but it doesn't seem to be working for scoped applications. 

Any response or help on this would be greatly appreciated.

Thanks!

var usertimezone = "Europe/London";

var ndt = new GlideDateTime();
gs.info("System Time is " + ndt);
var newtimezone = new GlideScheduleDateTime(ndt);
newtimezone.setTimeZone(usertimezone);
gs.info("User set time is " + newtimezone.getGlideDateTime().getDisplayValue());

@Anjali Priya 

setTimeZone() does work in scoped app

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());

If my response helped please mark it correct and close the thread so that it benefits future readers.

Hi @Anjali Priya 
I have some Script Snips that will Help :-

// Step 1: Create GlideDateTime object with current CET time
var gdt = new GlideDateTime(); // current system time (UTC-based)

// Step 2: Get CET offset manually
var cetTZ = java.util.TimeZone.getTimeZone("CET");
var cetOffsetMillis = cetTZ.getOffset(new java.util.Date().getTime());

// Step 3: Add CET offset to UTC
var cetDate = new GlideDateTime();
cetDate.add(cetOffsetMillis / 1000); // converting ms to seconds

// Step 4: Format CET time
var cetJavaDate = cetDate.getDate().getJavaObject();

// Step 5: Convert to user-input timezone
var targetTZ = java.util.TimeZone.getTimeZone(targetTimeZone);
var sdf = new java.text.SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
sdf.setTimeZone(targetTZ);

var userTime = sdf.format(cetJavaDate);

gs.info("Converted CET time to " + targetTimeZone + ": " + userTime);
