Set SetWorldTime( 23); inside a timer, that sets the time 23 always.

pawn Код:

forward SettingTime();
public SettingTime()
{
     SetWorldTime( 23);
     return 1;
}

and in OnGameModeInit:

pawn Код:

SetTimer("SettingTime", 600000, 1); // This will set time to 23 every 10 minuttes

preferably put SetWorldTime( 23); inside another timer you have
