GetPreviousOccurrence

[andr3marra]

Hello, I want to know how I can get a Previous Ocurrence from a Cron expression. I tried reading the source code but couldn't understand how it works. The only i could get it is expression.GetOccurence(DateTime.MinValue.ToUniversalTime(), fromUTC).Reverse().Skip(1).First(). Is there a better way to do this?
Does this request makes sense to add as a feature? If so what can I read to better my understanding of the algorithm used so I can implement it myself.
Ty in advance
