OVERVIEW The DateTime::TimeZone modules provide a Perl interface to the Olson time zone database. Rather than using the database directly, we parse the database files and turn them into a set of modules, one for each time zone defined. This allows for various optimizations in doing time zone calculations. This conversion is done with the script in tools/parse_olson. The Olson time zone database is the best available source for world wide time zone information. It is available from ftp://elsie.nci.nih.gov/pub/. A good starting point for information on the database, and time zones in general, is http://www.twinsun.com/tz/tz-link.htm. INSTALLATION To install this module type the following in the distribution directory: perl Makefile.PL make make test make install This distribution is dependent on DateTime.pm, but it does not list it as a prerequisite. This is because DateTime.pm is in turn dependent on this distribution, and we don't want to create a cyclical chain of prerequisites! This distribution will skip its tests if DateTime.pm isn't yet installed. If this weren't done, then neither module would be installable via CPAN. But this distribution's functionality only works in concert with DateTime.pm.
