Question : How to increase the Quest Delay - Lua Scripts

[Shakugan]

Hello community,

is there any option to incease the quest delay via lua script.

I know, that i can add this :

LuaSetAchievementLimit(1)
LuaSetDivideType(5)
LuaSetRealTime()

to add a 24h delay on a quest.

Is it possible to change it to 2h, or 10h, or 72h ?

Can anyone explain maybe, how i can do this?

Are this function hard coded in Gameserver.exe ?

If yes, is it possible to add new lua function to gameserver?

Thank you, i cant find anything about this topic.
