+Statefull assert, only `int` type arguments. Analogue to `limit`, but `interval_began` is initially set to `month(valid_from)` and set to `month(now)` on update, additionally the time assert is `month(now) >= interval_began + interval_in_months` (include logic for month overflow when year changes).
 
 ### Simple Example
 Assume account A and B and some unrelated key K. Furthermore A has a custom active authority in the following way:
