No useless info should be displayed in the console, now.

Now, every player should have their own local time properly stored.
When they do the /clear_scoreboard, it's removing them from the updating date method, so the scoreboard is not displaying for them.

If you find any bug, please tell me quickly so I can fix it.

The scoreboard should now dynamically update for each player, changing second by second.
The data displayed is no longer static; it reflects real-time changes.
