It has a option for Groovy script, but where can we get that script which will fulfil this requirement? I tried below script, but its not working

import com.hp.ov.nms.*
import java.text.SimpleDateFormat
import java.util.concurrent.TimeUnit

// Define the time threshold (15 minutes)
def timeThreshold = 15 * 60 * 1000 // 15 minutes in milliseconds

// Get the current time
def currentTime = System.currentTimeMillis()

// Define the date format for parsing the received time
def dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'")

// Function to convert a date string to milliseconds
def parseDateToMillis(String dateStr) {
try {
return dateFormat.parse(dateStr).getTime()
} catch (ParseException e) {
e.printStackTrace()
return 0
}
}

// Fetch all open events
def openEvents = Event.getEvents([status: "Open"])

openEvents.each { event ->
def receivedTime = event.getReceivedTime()
def receivedTimeMillis = parseDateToMillis(receivedTime)

if (currentTime - receivedTimeMillis > timeThreshold) {
// Close the event
event.close("Automatically closed due to 15-minute inactivity")
println("Event ${event.getId()} closed due to 15-minute inactivity.")
}
}
