Question

You are modernizing a legacy Python billing module that stores and compares timestamps using naive datetime.datetime.now() calls throughout. Customers in multiple regions have reported incorrect invoice cutoff times. You want GitHub Copilot to help migrate the code to be timezone-aware without altering the module's public function signatures. What is the most effective way to get a correct, scoped modernization from Copilot?

Accepted Answer

Open the module, select the datetime-handling functions, and use Copilot Chat with a prompt that states the goal (convert naive datetimes to timezone-aware UTC internally), the constraint (keep existing public signatures unchanged), and the target library (e.g., zoneinfo), then review each suggested change.

Answer

Ask Copilot in a fresh chat to 'fix all the date bugs in my project' so it can autonomously rewrite every file that touches dates.

Answer

Accept the first inline completion Copilot offers when you retype datetime.now(), since completions are always aware of the correct timezone for your users.

Answer

Rely on Copilot to infer the correct customer regions from the runtime, since it retains prior invoice data from earlier sessions to determine each timezone.
