[Weekly/Monthly Player Buff]

Hello,

Totally new at this ... 

I am trying to create a mod that gives all the players a buff one time per (real time) week or month, for 1h.

I am assuming there is no existing trigger for this (FirstLoginOfTheWeek/Month) !?

Any way to achieve it ?

 

I am thinking that:

- I may be able to build a variable to hold the real time ... ?

.. or

- Have a dummy buff for a week minus 1 hour ... and start the real one for 1 hour when the first expires .. but the first one should count time when the player is offline as well ...

 

Any hints ?

Thank you!
