[Haskell] ANN: time-1.4.0.2

[José Pedro Magalhães]

Could CPP be used instead so that if it's GHC it just derives Typeable?
Something similar seems to already be done for Data...

I'm asking because with the upcoming changes to Typeable these manual
instances will become problematic, and time is required to build GHC.


Thanks,
Pedro
