Hi, I've come across this sort of data constructor below many times but I'm not really sure how to use it. Can someone please point me to the right section in the documentation? In particular, I want to know how to create a calendar time and how to access the fields . Tom data CalendarTime = CalendarTime { ctYear :: Int, ctMonth :: Month, ctDay, ctHour, ctMin, ctSec :: Int, ctPicosec :: Integer, ctWDay :: Day, ctYDay :: Int, ctTZName :: String, ctTZ :: Int, ctIsDST :: Bool } deriving (Eq, Ord, Read, Show)
