DateTime::TimeZone :: dieing on non existing timezone

[Mathieu]

Hi,
 i'm looking for a way to find out if a timezone is valid.
If i want to check a timezone using this module i instanciate
an object with the provided name:
 my $otz = new DateTime::TimeZone( name => 'Europe/Paris' );
This name is valid so no problem, but if i try:
 my $otz = new DateTime::TimeZone( name => 'Europ/Paris' );
the module dies and so my script.
I've modified the DateTime::TimeZone module so that it returns
undef when the timezone name is not valid.
Is this the proper way to do it, or is there a simple solution
to my problem i didn't spotted ? If it's the proper way is there
any chance it will be included in a future release ?
Thanks.

Mat
