What was unclear or otherwise insufficient?

I'm a first-time contributor to TypeORM, and when I tried npm run test for the first time then the test case issue-9230 failed due to date formatting.

After some troubleshooting, I realized that using TZ=UTC allowed the test to pass.

Recommended Fix

Update the DEVELOPER.md instructions for running tests to let users know they may need to adjust the timezone used by the tests by setting a temporary environment variable.
