Usage

<dependency>
    <groupId>com.infilos</groupId>
    <artifactId>relax-timer</artifactId>
    <version>LATEST</version>
</dependency>

And, add a binding for slf4j:

<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>LATEST</version>
</dependency>

And then create time instance and submit tasks:

Timer timer = Timer.create("test-timer").startup();

// print "run..." after 2 seconds
timer.submit(new Runnable() {
    @Override
    public void run() {
        System.out.println("run...");
    }
}, 2000L);
