I am trying to convert the Twitter created_At timestamp to another timestamp using NSDateFormatter. However it took me a while to work out the date style for the timestamp.

Is there any documentati开发者_开发百科on out there than includes all the codes/date styles that can be used with the NSDateFormatter?

P.S. Anyone that needs the style it is: eee MMM dd HH:mm:ss ZZZZ yyyy.

Two pieces of documentation to check out. The first is the Date Formatting Guide. It gives an overview of all of the options and uses. The other thing to check out is the Unicode Technical Standard #35. It's what NSDateFormatter uses for the formatting patterns and lists out what all the different date field symbols are.
