Hello all,

Just a friendly reminder that you may get help from the A0 Time Zone Migration utilities to programatically get the diffs between tzdb releases, so you can check/correct your data once a new tzdb is installed in your systems.

Documentation for this OSS project is at: https://a0.github.io/a0-tzmigration/ for ruby and javascript.

Examples of latest changes from 2018e to 2018f for:

- Europe/Volgograd

https://a0.github.io/a0-tzmigration/demo/?ta=Europe%2FVolgograd&va=2018e&tb=Europe%2FVolgograd&vb=2018f&m=timeline

- Pacific/Fiji

https://a0.github.io/a0-tzmigration/demo/?ta=Pacific%2FFiji&va=2018e&tb=Pacific%2FFiji&vb=2018f&m=table

- America/Santiago

https://a0.github.io/a0-tzmigration/demo/?ta=America%2FSantiago&va=2018e&tb=America%2FSantiago&vb=2018f&m=timeline

from 2018f to 2018g for:

- Africa/Casablanca:

https://a0.github.io/a0-tzmigration/demo/?ta=Africa%2FCasablanca&va=2018f&tb=Africa%2FCasablanca&vb=2018g&m=timeline

Getting the same diff in code is as simple as the following:

import { TZVersion } from 'a0-tzmigration-js'

// calculate changes from America/Santiago 2018e to America/Santiago 2018f

let version_a = new TZVersion('America/Santiago', '2018e')

let version_b = new TZVersion('America/Santiago', '2018f')

let changes = await version_a.changes(version_b)

console.log(changes)

HTH,
