  • I am new to Groovy. As an system admin, just try to do a quick script. The date/time output from JIRA is like this and I need to compare it to the current time. – user1288329 Mar 9 '15 at 14:14

Based on the requirements you have put down I assume that you already have the date somewhere in code (if not check out com.atlassian.jira.component.ComponentAccessor). As for comparing the dates here is a short script and if you need more dates then just stack them up in an array and loop through them.

    import java.text.SimpleDateFormat;
    import java.util.*;

    class DateTimeComparer
        public Date convertDateTime(String element) throws Exception
            SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MMM/yy HH:mm a");
            return dateFormat.parse(element);

        public static String compareDateTimes(Date date1, Date date2)
            if (date1.after(date2)) return "date1 is after date2";    

            if (date1.before(date2)) return "date1 is before date2";

            if (date1.equals(date2)) return "date1 is equal to date2";

        public static void main(String[] args) throws Exception 
            DateTimeComparer dateTimeComparer = new DateTimeComparer();

            Date convertedDate = dateTimeComparer.convertDateTime("21/Sep/12 2:01 PM");
            Date today = new Date();

            String comparedDates = dateTimeComparer.compareDateTimes(today, convertedDate);

            println comparedDates;
