boss timers

was wondering would it be possible to get a timmer the boss times. or liek a way to summon them, or basically anything so we dont have to wait for 12 hoursto get to fight a bloody world spawn boss

the only boss u have to wait are manon/griffey/all mushmoms/black crow/ah ma(the one b4 amoury)/pianus.
the only ones u can summon are zak/pap, horntail if it is working.

if all mob can be summon
it makes the game less interesting.
if u wan to summon
then make ur own private server
making ur own code for npc and map
and u can summon it

IMO: making a private server takes weeks to months to complete. so dont complain abt anything on the server u are playing right now.
