A parser and renderer for binary Olson timezone files whose format is specified by the tzfile(5) man page on Unix-like systems. For more information about this format, see http://www.iana.org/time-zones/repository/tz-link.html Functions are provided for converting the parsed data into TimeZoneSeries objects from the timezone-series package. On many platforms, binary Olson timezone files suitable for use with this package are available in the directory usrshare/zoneinfo and its subdirectories on your computer.
