This is the haskell time library that is bundled with GHC the Glasgow/ Glorious Haskell compiler.
To build this package using Cabal directly from git, you must run "autoreconf" before the usual Cabal build steps (configure/build/install). autoreconf is included in the GNU autoconf tools. There is no need to run the "configure" script: the "setup configure" step will do this for you.
