EDIT:
On top of script

Код:

new changedtime, Time;

In the function which is running with a timer of 2 second

Код:

if(gettime() - changedtime > 12000)
{
     foreach(Player, i)
     {
          if(Time > 24) Time = 1;
          else Time++;
          SetPlayerTime(i, Time, 0);
          changedtime = gettime();
     }
}
