title: Updating all packages in GHC global package db to latest versions
body: <p>I am trying to install the latest versions of all the Hackage packages that I use, and I would like to update the packages that ship with GHC 7.6.3 (except maybe for the base package) to their latest versions.</p>
  
  <p>Is there an easy way to do this?</p>
  
  <p>If there is not an easy way to update all the packages in GHC's global package db, is there an easy way to update the [time] package in the global package db to the latest version?</p>
  
  <p>Regards
