在Django中获取系统时间w / timezone绕过默认时区

Question

As long as I'm using plain ol' Python shell, the datetime.datetime.now() command works fine to get system's local (non-UTC) time.

But I'm working on a Django project where the time zone is changed in settings.py with TIME_ZONE = 'UTC' .

I've tried many solutions from django.utils timezone to tzlocal module, but none of them works. All of them return either incorrect or UTC time.

All of the solutions work if I change the timezone in settings.py to my local timezone. But I can't do that, so is there any way to bypass the default timezone option in settings.py ? Or any way the settings.py 's timezone can be automatically updated? If I remove the TIME_ZONE line, I don't know why, but it seems to get a random timezone.

EDIT -

I know that the timezone can be entered manually with pytz , but I don't want to do that. I want to get the local system timezone, but WITHOUT Django's moderation of the timezone.

Thanks.

Answer 1

To get the time for a different timezone, use this code:

# create another timezone instance
import pytz
new_york_tz = pytz.timezone("America/New_York")

# get the current date and time, with the timezone set in your settings.py
from django.utils import timezone
d = timezone.now()
print(d)

# get the date and time in your other timezone
d2 = new_york_tz.normalize(d)
print(d2)

Answer 2

Django seems to be putting its timezone in the TZ environment variable. Try del os.environ['TZ'] then using tzlocal.

You can use Javascript to get the Timezone Offset from browser to UTC. Here is the code.

var d = new Date()
var n = d.getTimezoneOffset()
alert(n)

The result is the amount of minutes. For example, you will get 480 in Los Angeles. if the result is negative number, the timezone should be the "West", opposite, the positive number means "East". AND 1 timezone = 60 minutes, so, you can figure out 480 / 60 = 8. Then the result is Los Angeles is in the west 8 timezone. Then you can use pytz to get the local time.
