Any plans to offer TypeScript typings (package.json =>"typings") ?

@zam6ak see #341

Why this has more info for Argentina country than master?
Could we add that info to the latest on master?

@mj1856 : Hi... Any plans for a review in the near future?

[brettz9]

With Bower deprecated as a service, maybe the bower.json part of the to-dos can be dropped entirely?

@timrwood How is this going?

[pdesjardins90]

@mj1856 did you take over this? You need any help? I'd like this to move forward

[pdesjardins90]

@timrwood @mj1856 @ichernev @ellenaua anyone can revive this? I can help too

[mattjohnsonpint]

I'm going to close this, just because of how much time has passed. Sorry we never got it done, but sometimes life takes over. At this point, I don't plan on making changes this drastic to moment-timezone.

The go-forward plan for moment and moment-timezone users is Luxon. It already has time zone support and is fully modularized ES6.

Thanks for the feedback and recommendation, will migrate to luxon then
