I see London and Dublin, with Belfast a link to London.

I'm not aware of the full common names of time zones anywhere
in the database, just the abbreviations; so the string, "Greenwich
Mean Time", probably comes from the "company's application
servers" that the author mentions.

Which is why the summer-time abbreviations are BST and IST,
respectively.  Maybe the "company's application servers" aren't
picking that up.

Does that make sense?
