Excellent - too many apps don't have this.

'all_names' should return all that you need.

You really don't want to do that.
Many users don't really understand timezones, but almost all know
where they are. As an example - say you are in the UK and it is mid
April - should you choose GMT or GMT+1? Has BST kicked in yet? And
will you remember to log in again and change your settings when BST
ends, whenever that is. Choose 'Europe/London' and all the magic
happens for you.
Also these timezone names can be localised for your users if you ever
change the language of your site.
Don't forget to be religious about storing all times as UTC in your
database etc.
Cheers,
Edmund.
