Grails : Difference b/w two dates with fine-grained details

Hi Friends,

To retrieve difference between two dates with finer details which would display their difference as 2 years 7 weeks 3 days 2 hours 5 mins ago is given below.

 /**
   * Returns differnce b/w new Date and old date as Map holding difference in years, weeks, days, hrs, mins & secs 
   */
  public static Map getDiffernceInDates(Date oldDate, Date newDate = new Date()) {
    Long difference = newDate.time - oldDate.time
    Map diffMap =[:]
    difference = difference / 1000
    diffMap.seconds = difference % 60
    difference = (difference - diffMap.seconds) / 60
    diffMap.minutes = difference % 60
    difference = (difference - diffMap.minutes) / 60
    diffMap.hours = difference % 24
    difference = (difference - diffMap.hours) / 24
    diffMap.years = (difference / 365).toInteger()
    if(diffMap.years)
       difference = (difference) % 365
    diffMap.days = difference % 7
    diffMap.weeks = (difference - diffMap.days) / 7  
    return diffMap
  }
  

The taglib to display the date difference in detail is given below

def timeDiffInDetail = {attrs ->
        Map diff = DateUtil.getDiffernceInDates(attrs.oldDate, attrs.newDate ?: new Date())
        String result =  diff.years ? diff.years + " years " : ""
        result += diff.weeks ? diff.weeks + " weeks " : ""
        result += diff.days ? diff.days + " days " : ""
        result += diff.hours ? diff.hours + " hours " : ""
        result += diff.minutes ? diff.minutes + " minutes ago" : ""
        if (result)
          out << result
        else
          out << " 0 minutes ago"
}

Hope this helpled!

Cheers!
