Olson::Abbreviations -globally unique timezones abbreviation handling

This module should help you with converting commonly used and often ambigious olson abbreviations into TZ offset notation.

This module is released as 0.01 because it is useful. It is not complete. In order to be complete in the author's eyes this module must accept a locale and disambiguate based on that.

EST is not ambigious if your standing in the US or in Austrailia. This module should handle this properly in the future.

Quick summary of what the module does.

Perhaps a little code snippet.

    use Olson::Abbreviations;

    my $oa = Olson::Abbreviations->new({ tz_abbreviation => 'EST' });
                $oa->is_unambigious; # returns 0
                $oa->is_known;       # returns 1
                $oa->get_offset      # dies

Returns the offset to UTC
Returns 0|1 based on if the abbreviation is globally unambigious to the whole planet
Returns 0|1 based on if the abbreviation is known despite if it is ambigious or not
