You need to give us more information then that, what do you want this command to achieve? The best way, in my opinion would be to use a timer, which I already use to update the hours. Then just add a variable to it let's name that "World24" so after updating every hour, I'd have the command like:

pawn Код:

CMD:world(playerid, params[])
{
if(World24 == 24) // If the World24 = 24 Full day.
{
//code
World24 = 0;
}
return 1;
}

Not a full command, just an example.
