The goal of this package is to provide a library that can read time zone info files (aka. Olson files), and does time zone conversions in a pure and efficient way. We also provide platform-independent and/or compiled-in access to the standard Time Zone Dabase by the means of the companion tzdata package http://hackage.haskell.org/package/tzdata. The package is currently in an alpha phase, I'm still experimenting with different ideas wrt. scope/API/implementation/etc. All comments are welcome!
