commit e6d887a4eb63a9971ba86d84222e809f3c20373c
Author: Herbert Valerio Riedel <hvr at gnu.org>

    Add support for `deepseq-1.4.0.0`
    
    `deepseq-1.4.0.0`'s major change is the default `rnf` method implementation
    (see haskell/deepseq#1 for details).
    
    This commit changes `time` not to rely on the default implementation and
    instead explicitly make use of `seq` like the old default implementation did.
