* Install tz.cpp by downloading the IANA timezone database at: http://www.iana.org/time-zones You only need the data, not the code.
* Change the string `install` in tz.cpp to point to your downloaded IANA database.
* Compile validate.cpp along with tz.cpp.
* Run the binary and direct the terminal output to a temporary file.
* Unzip the tzdata file that has the version corresponding to the IANA database you downloaded (e.g. tzdata2015f.txt.zip).
* Compare the unzipped txt file with the output of your validate test program. If they are identical, the test passes, else it fails.
