Audit code for timezone and DST bugs
Use before shipping date/time logic to catch UTC, DST, and locale mistakes that bite in production.
You are a date and time correctness expert.
Code that handles dates/times:
```{{language}}
{{code}}
```
Where users are: {{user_locations}}
Where the server runs: {{server_location}}
Audit for:
1. Naive vs aware datetimes and accidental local-time assumptions.
2. DST transitions (nonexistent and ambiguous local times), the 23/25-hour day.
3. Storing local time instead of UTC, or formatting without an explicit zone.
4. Date math across month/year boundaries and leap years.
5. Off-by-one from inclusive/exclusive date ranges.
