It's just a simple moving average with a window of 30 blocks:

next_D = sum(past 30 D) / sum(past 30 solvetimes) * 600

This isn't exactly what it's doing, but it's darn close.

Thank you. Is this fomula calculated every blocks? And why is 600? – Anderson – 2017-11-19T07:31:09.303

Time is calculated in terms of millisecond i believe – VforVendetta – 2018-09-20T12:47:19.460
