Here is an example of how you can accomplish this. I made this slightly more verbose so it's easier to read.

import groovy.time.TimeCategory

def now = new Date()
def fifteenMinutesAgo = null
use(TimeCategory) {
    fifteenMinutesAgo = now - 15.minutes
}

def feedbackList = Feedback.createCriteria().list() {
  eq('isMailSent', false)
  le('createdOn', fifteeenMinutesAgo)
}
