Summary of Changes

Hello @knit-pay, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request resolves deprecation warnings introduced in PHP 8.5 by updating method signatures to explicitly declare nullable DateTimeZone parameters. This ensures forward compatibility and adherence to modern PHP type hinting standards, preventing runtime warnings in environments running PHP 8.5 or newer.

Code Review

This pull request correctly addresses a deprecation warning in PHP 8.5 by making the $timezone parameter explicitly nullable in the create_from_format method. The changes are accurate and focused. I've added a couple of suggestions to update the corresponding PHPDoc blocks to maintain consistency between the code and its documentation.
