Reliable source for area codes and time zones

[Alexis_D_Alba1]

I'm creating smart lists for all the timezones and want to make sure i'm using the most accurate data. If someone can recommend a source that you use and trust that would be great.

Thanks = )

The BDR team at my previous role called all over the world and heavily relied on https://www.worldtimebuddy.com/​. They loved it, said the time zones listed were always correct!

FTR, if you want up-to-date tz info, there -- legally and technically -- cannot be a more authoritative source than the official Time Zone Database. You can subscribe to the mailing list here​ or a (Java-centric) RSS feed here.

Subscribing will cue you in to upcoming changes, some of which are significant shifts. Of course their relevance will depend on your audience (did you know that Antarctica shifted to be 3 hours later in 2016?).
