Need help for new drow items disintegration script

[Turambar90]

I'm writing a new tweak, which should correct many problems in the similar component from BG2Tweaks.

 

I have some questions about how to make checks for the disintegration effects under specific circumstances (every hour outdoors when it's day; when hit by sunray ; when a weapon is used in the sunlight). Could you please help me? I've written the details here; could you please have a look to these questions (and reply there, in order to have just one thread?)

TIA for any help
