Moment-timezone Import Cost

[bsaracalign]

Moment-timezone version which you use:

Version: "^0.5.40"

Note: many issues are resolved if you just upgrade to the latest version

Issue description:

Import cost for this package is 836.4k (gzipped:59.2k) that's an extremely large size. I understand there may be many reasons and even current development, Is there any place you share for current developments to decrease import cost of this package? Also I do import by import moment from 'moment-timezone' is there a more preferable import that'll help?

The overall package size is discussed at #999 — that's the best issue to follow to get updates.

To answer your other question, I've recently added some extra details into the Node.js section of the documentation. Specifically, if you want to avoid the default data file, you can do the following:

import moment from 'moment-timezone/moment-timezone';
moment.tz.load(customData);

The custom data format is described in the Data Loading section, and can be created in a local build step using the filterLinkPack() utility method.
