I have encountered a problem with the make_aware function used in Django
for converting naive datetime objects to aware datetime objects.
Steps to Reproduce:
1. Create a naive datetime object that falls within a DST transition
period.
2. Call make_aware with this naive datetime and a timezone that observes
DST.
3. Observe the incorrect timezone conversion.
Code Snippet to reproduce issue
{{{
from datetime import datetime
import pytz
from django.utils.timezone import make_aware
time_str = "2024-10-22"
time_obj = datetime.strptime(time_str, "%Y-%m-%d")
shanghai_tz = pytz.timezone("Asia/Shanghai")
pytz_aware_time = shanghai_tz.localize(time_obj)
django_aware_time = make_aware(time_obj, timezone=shanghai_tz)
print(f"pytz_aware_time: {pytz_aware_time}")
print(f"django_aware_time: {django_aware_time}")
}}}
Output:
pytz_aware_time: 2024-10-22 00:00:00+08:00
django_aware_time: 2024-10-22 00:00:00+08:06
Environment:
- Django version: Django 5.0.9
- Python version: Python 3.12
- Operating system: macOS Sonoma 14.5
