How to get the End Date for the schedule

[rubesh_u]

I am using this script. when the planned start or planned end date falls on blackout window it is not working as expected it stops at 18:00 

function getBlackoutDatesWithinRange(scheduleId, plannedStartDate, plannedEndDate) {

var timeZone = session.getTimeZoneName();

var scheduleGUID = scheduleId;

var schedule = new GlideSchedule(scheduleGUID);

schedule.setTimeZone(timeZone);

var gdt = new GlideDateTime(plannedStartDate);

var gdte = new GlideDateTime(plannedEndDate);

// gs.log(schedule.getNextOccurrence());

// Set the start to the beginning of the day (midnight)

var sd = new GlideDateTime();

sd.setValue(gdt.getDate() + " 00:00:00");

// Set the end to the end of the day (23:59:59)

var ed = new GlideDateTime();

ed.setValue(gdte.getDate() + " 23:59:59");

// Log the actual start and end times

// gs.log("Start Date: " + sd.toString());

// gs.log("End Date: " + ed.toString());

var ssd = new GlideScheduleDateTime(sd);

ssd.setTimeZone(timeZone);

var sed = new GlideScheduleDateTime(ed);

sed.setTimeZone(timeZone);

var scheduleMap = schedule.getTimeMap(sd, ed, timeZone);

// gs.log(scheduleMap);

var span = new GlideScheduleDateTimeSpan(ssd, sed);

var thisMap = new GlideScheduleTimeMap();

thisMap.addInclude(span);

thisMap.buildMap(timeZone);

var overlaps = scheduleMap.overlapsWith(thisMap, timeZone);

overlaps.buildMap(timeZone);

var dates = [];

while (overlaps.hasNext()) {

var overlapSpan = overlaps.next();

var glideStartDate = overlapSpan.getStart();

var glideEndDate = overlapSpan.getEnd();

gs.log(glideStartDate);

// var plannedTaskAPI = new SNC.PlannedTaskAPI();

// var resp = plannedTaskAPI.calculateDuration(JSON.stringify(glideStartDate), JSON.stringify(glideEndDate), scheduleGUID);

// gs.log(resp);

gs.log(gs.dateDiff(glideStartDate, glideEndDate, false));

dates.push({

startDate: overlapSpan.getStart().toString(),

endDate: overlapSpan.getEnd().toString()

});

// gs.log(overlapSpan.getDuration());

}

return JSON.stringify(dates);

}

// Test case with logging

gs.log(getBlackoutDatesWithinRange("126760263b69169053ba5c7aa5e45a01", "2025-02-12 23:59:59", "2025-02-15 00:00:00"));

*** Script: 2025-02-15 00:00:00
*** Script: 17:59:59
*** Script: [{"startDate":"2025-02-15 00:00:00","endDate":"2025-02-15 17:59:59"}]

but expected should be

*** Script: 2025-02-15 00:00:00
*** Script: 17:59:59
*** Script: [{"startDate":"2025-02-15 00:00:00","endDate":"2025-02-16 23:59:59"}]
