It's utility class for robots time profiling. Feel free to adopt and/or use it

Usage (typed in browser, so may contains errors):

public class TPRobot extends AdvancedRobot {

    static {
        TimeProfile.initBattle();
    }

    public void run() {
        TimeProfile.initRound();
        while (true) {
            TimeProfile.initTurn();
            TimeProfile.TURN_TIME.start();
            // robot code
            TimeProfile.TURN_TIME.stop();
            execute();
        }
    }

    public void onDeath(DeathEvent event) {
        System.out.println(TimeProfile.getRoundProfilesString());
        System.out.println(TimeProfile.getBattleProfilesString());
    }

    public void onWin(WinEvent event) {
        System.out.println(TimeProfile.getRoundProfilesString());
        System.out.println(TimeProfile.getBattleProfilesString());
    }

    public void onSkippedTurn(SkippedTurnEvent event) {
        System.out.println(TimeProfile.getTurnProfilesString());
    }

}
