Another question: Can I unpack some fields in a record and not unpack
others? Does their order matter then?

Oh, I see, thanks!
So then, I guess, the solution would be to use a fixed-precision integer type instead.

newtype Day = ModifiedJulianDay {toModifiedJulianDay :: Integer} newtype DiffTime = MkDiffTime Pico
And Pico is also essentially a newtype for Integer.
So, I'm getting warnings on this definition of UTCTime. QUESTION: Is it the case that I can only UNPACK primitive fields, and not even their newtypes?
The problem is that you can't {-# UNPACK #-} Integer. You can only unpack single-constructor types.
