Thnx a lot. Is it possible to make a list like:

Europe
   Amsterdam (CET)
    etc
Africa
   ..
[download]

So far I can:

my @cat = DateTime::TimeZone::categories() ;
foreach (@cat) {
my @b =     DateTime::TimeZone::names_in_category( $_ ) ;
  print "$_:\n" ;
  foreach (@b) {
    print "      $_\n" ;
  }
 etc ;
}

How do I convert something like Africa/Abidjan to a short name abbreviation ?
