How do I set a timezone in my Jest config?

Question

✗ npx jest --version
24.5.0

Got a set of jest tests that are timezone sensitive. We typically run them with an npm script: \"jest\": \"TZ=utc

Answer 1

I just run into the same issue and I was able to resolve it by adding process.env.TZ = 'your/timezone'; to my jest.config.js.

Maybe this helps in your case as well :)

process.env.TZ = 'UTC';

module.exports = {
  ...
};
