Allow multiple abbreviations / alternate names

[KevinNovak]

I'm writing an application that needs to detect a time zone based on user input, including abbreviations. Some users may type type something like "PDT" or "PT" instead of "PST" or vice versa, so it would be useful to maybe make the abbreviations an array, or have a preferred abbreviation and then a list of alias abbreviations. I think this logic could also be applied to the alternate names as well, if necessary.

Hi, if there's a list somewhere we can use and automatically read from then why not! I'll be accepting PRs trying to solve this, yes
