constField of current year?

[mmynsted]

How do I create a `constField` with key "thisYear"?

I am sure it is some combination of `unsafeCompiler getCurrentTime` and 

`formatTime defaultTimeLocale "%Y"` but I have not found the right arrangement. 

If I do something like this:

```

let z = do 

  t <- getCurrentTime

  pure $ formatTime defaultTimeLocale "%Y"

```

Then z is an IO String as I would expect, with the correct value.

Then I would need to enlist `unsafeCompiler` to move me from the IO to Compiler...

What am I missing?

Maybe there is a better way, but this worked for me.

timeCtx :: Context a

timeCtx =

   field "thisYear" ( \_ -> do

     t <- unsafeCompiler getCurrentTime

     pure $ formatTime defaultTimeLocale "%Y" t

   )

Yep, that's a good way to do it! I'm using something similar here:
