@michaelpj I was able to reproduce the old behaviour I was seeing using an older version of GHC / HLS:  Steps: * Checkout `60d531be17a6fd99a9a73f80b6682f5e371d5a04` from https://github.com/serokell/tztime (this commit uses...

Ah, I first thought you meant some internal flag that was easy to spot and change in v4. The first two approaches that come to mind are: - Simply add...
