type EpochTime = CTime
newtype CTime = CTime Int64
You can just pattern match.

Dear Haskell cafe,
I want to convert form
mtime :: System.Posix.Types.EpochTime
to something aeson can eat without having to define an instance. I choose Integer.
My current solution[1] is just using (read . show). I know, ugly, but the only thing I could get going.
What is the proper way to convert System.Posix.Types.EpochTime to Integer or something else aeson will automatically convert without making a ToJSON instance?
As a beginner I wonder: is there a general way to go about finding conversion paths between types?
Greetings,
Bram Neijt
