This is a fork of (Bigeasy's Timezone library)[https://github.com/bigeasy/timezone].

The original library uses eggert/tz to generate up-to-date timezone information, but the library is not maintained anymore. This fork uses (@instructure/timezone)[https://github.com/instructure/timezone]

If time zones ever get out of sync again, do the following...
``bash
git clone --recurse-submodules [@instructure/timezone URL]
cd timezone
cd eggert/tz
git checkout [Last updated version number from moment-timezone, e.g. 2023c]


update package.json version number

npm install
make publish # publishes to NPM
git add .

commit and push git changes

`javascript
var tz = require('timezone/loaded'),
equal = require('assert').equal,
utc;

// Get POSIX time in UTC.
utc = tz('2012-01-01');

// Convert UTC time to local time in a localize language.
equal(tz(utc, '%c', 'fr_FR', 'America/Montreal'),
'sam. 31 déc. 2011 19:00:00 EST');
`
