Well no its the wrong way of doing it
You gotta set timer at the time the wanted level is increased

pawn Код:

timid[MAX_PLAYERS];//on top
/*===================================*/

//this when player wanted level is increased
KillTimer(timid[playerid]);
timid[playerid]= SetTimerEx("ReduceWantedLevel", 60000, false, "i", playerid);

/*=====================================*/

//the public function to reduce it
forward ReduceWantedLevel(playerid);
public ReduceWantedLevel(playerid)
{
SetPlayerWantedLevel(playerid, GetPlayerWantedLevel(playerid)-1);
return 1;
}
