There is a bug in Piotr Czapla's answer:

new RegexDateTimePattern (
            @"([2-9]\d*) *h(ours)? +ago",
            delegate (Match m) {
                var val = int.Parse(m.Groups[1].Value); 
                return DateTime.Now.AddMonths(-val);
            }
       ),

AddMonths is used instead of AddHours().

PS: I can't comment on his answer because of low forum points. I've already wasted time on debugging it of why it removes 5 days when I try with "5 hours ago".
