convert the 24 hr time format to 12 hr format

[RahulRAJAS]

Hi team
I have this code to fetch and display the date and time in CST but it is displaying in 24 hour format but how can I display it in hh:mm am/pm format?

   var time = new GlideDateTime();
var targetTimezone = 'CST'; 
var tz = Packages.java.util.TimeZone.getTimeZone(targetTimezone); 
time.setTZ(tz);
var timeZoneOffSet = time.getTZOffset();
time.setNumericValue(time.getNumericValue() + timeZoneOffSet);
template.print(time + " CST");

var time = new GlideDateTime();

// Use proper timezone ID for Central Time (handles CST/CDT automatically)
var targetTimezone = 'CST';
var tz = Packages.java.util.TimeZone.getTimeZone(targetTimezone);
time.setTZ(tz); // sets the timezone properly

// Get display value (yyyy-MM-dd HH:mm:ss)
var displayTime = time.getDisplayValue(); // e.g., "2025-09-18 07:08:45"

// Extract date and time parts
var datePart = displayTime.substring(0, 10); // yyyy-MM-dd
var hour24 = parseInt(displayTime.substring(11, 13)); // HH
var minute = displayTime.substring(14, 16); // mm

// Convert to 12-hour format with AM/PM
var period = "AM";
var hour12 = hour24;

if (hour24 == 0) {          // Midnight
    hour12 = 12;
    period = "AM";
} else if (hour24 == 12) {   // Noon
    hour12 = 12;
    period = "PM";
} else if (hour24 > 12) {    // Afternoon
    hour12 = hour24 - 12;
    period = "PM";
} else {                     // Morning
    hour12 = hour24;
    period = "AM";
}

// Build final time string
var finalTime = hour12 + ":" + minute + " " + period;

template.print(datePart + " " + finalTime + " CST");

this helped me to resolve my issue.
Thanks everyone for your replies and time.
