Plugin Help needed

Hello, I am trying to develop my plugin, and see some features are not working. I have the following commands:
/heal
/feed
/creative
/survival (Not working)
/time [day,night,morning] (Not Working)

The survival is exactly the like creative code, but it doesn't seem to work: Code for survival:

Code:java

                }else if(commandLabel.equalsIgnoreCase("survival")){
                    if (sender.hasPermission("LC.survival"))
                        if(args.length == 0){
                            player.setGameMode(GameMode.SURVIVAL);
                            player.sendMessage("ChatColor.GOLD + Gamemode set to Survival");
                        if(args.length == 1){
                            Player targetPlayer = player.getServer().getPlayer(args [0]);
                            targetPlayer.setGameMode(GameMode.SURVIVAL);
                            return false;
                        }

and then the time will not work at all for some reason:

Code:java

                }else if(commandLabel.equalsIgnoreCase("time")){
                    if(args[0].equalsIgnoreCase("day")){
                        world.setTime(0);
                        Bukkit.broadcastMessage("Time set to Day!");
                    }else if(args[0].equalsIgnoreCase("night")){
                        world.setTime(14000);
                        Bukkit.broadcastMessage("Time set to Night!");
                    }else if(args[0].equalsIgnoreCase("morning")){
                        world.setTime(1000);
                        Bukkit.broadcastMessage("Time set to Morning");
                        return false;
                        }

Please help asap. Any help is appreciated very much!
