Why and how does Django affect time.localtime?

Question

Django

I noticed that Django (apparently through the TIME_ZONE setting) affects the work of the built-in time.localtime function.
I thought that this function relies on the OS time zone, but dzhanga somehow influences it. How does this happen? and why?

Answer 1

Yes, django affects time.localtime() via os.environ['TZ'] and time.tzset() if USE_TZ=True is set. And unlike my assumption that django settings only affect django itself (django.utils.timezone.local()), it turned out that in the end ALL aware datetime.datetime created in such an environment will use the TIMEZONE slipped by django. Oh, those global variables.
