[SOLVED] How to estimate next difficulty?

[Soak]

Hello,

I'm trying to develop a tool that can say to me when the next difficulty when happen.

I want (estimations or not) :

• What block will apply next difficulty
• In how many time
• Next difficulty

I have :

• Current blocks
• Current difficulty

What I need too? And what formulas can apply to that please?

Thank you in advance.
