I'm using a NSDateFormatter to parse a RFC 822 date on the iPhone. However, there is no way to specify optional elements in the date format. There are a couple of optional parts in the RFC 822 specification which is breaking the date parser. If nothing works out, I'd probably have to write a custom parser to obey the specs. For example,...

I am interested in creating a method to find if the current date falls between certain times on any given day. It is for a scheduling program, so I want to find what event is occurring at the current time. Every day has the same set of times: 820-900, 900-940, 940-1020, etc. Since this must be done on any given day I do not know how to c...
