Summary of Changes

Hello @lahirumaramba, 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 streamlines the RFC3339 date-time parsing logic by removing a legacy workaround. The change leverages improvements in Python 3.7 and later, which natively support parsing timezone offsets containing colons, thereby simplifying the codebase and removing technical debt.

Highlights

• Timezone Parsing Workaround Removed: Eliminated a regex substitution and associated comments previously used to handle timezone offsets with colons in Python versions older than 3.7, simplifying the _parse_to_datetime function.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Changelog

• firebase_admin/_rfc3339.py
  • Removed a regex substitution that stripped colons from timezone offsets.
  • Deleted comments explaining the necessity of the workaround for Python versions prior to 3.7.

Code Review

This pull request removes a workaround for parsing RFC3339 date strings on Python versions older than 3.7. The change is a simple deletion of obsolete code, which correctly relies on the improved datetime.strptime functionality in modern Python versions. This improves code clarity and maintainability. The change is correct and I have no suggestions for improvement.
