domainage.groovy

import org.jsoup.Jsoup
import org.jsoup.nodes.Document

def DAYS_IN_YEAR = 365

Document doc = Jsoup.connect("http://wayback.archive.org/web/*/${url}").get()
String date = doc.select("#wbMeta p.wbThis a")[1].attributes().href.split('/')[2]
Date firstIndexDate = Date.parse('yyyyMMddHHmmSS', date)
use(groovy.time.TimeCategory) {
    def duration = new Date() - firstIndexDate
    println Math.round(duration.days / DAYS_IN_YEAR * 100) / 100
}
