This is a Java port of the jquery-timeago plug-in.
The org.github.timeago project contains a Maven pom.xml file that builds a jar containing the TimeAgo class.
To build and run the included unit tests: $ mvn clean install
TimeAgo time = new TimeAgo();
String minutes = time.timeAgo(System.currentTimeMillis() - (15*60*1000)); // returns "15 minutes ago"
