UTCTime codec

[Dustin Sallings]

Aeson has a lot of code for transcoding UTCTime, so I assume compatibility might be non-trivial, but something like might be a starting point:

instance HasCodec UTCTime where
  codec = bimapCodec fromText toText textCodec
    where
      fromText t = maybe (Left $ "can't parse time: " <> show t) Right . formatParseM iso8601Format $ T.unpack t
      toText = T.pack . formatShow iso8601Format  -- this is theoretically partial

I immediately found one in the code that wasn't showing up in the docs. :/

For backward compatibility reasons, the codec that autodocodec uses must encode and decode values in the same way.
That's why we use codecViaAeson in the current version.

Are you using the latest version?

[Dustin Sallings]

Nope. I'm looking at an older snapshot. Trying with a later one.
