这是我测试TIME_ZONE和`USE_TZ的作用的代码：

from django.test.utils import override_settings

class TimeZoneTest(TestCase):

    @override_settings(TIME_ZONE='UTC', USE_TZ=True)
    @freeze_time("2018-01-04 13:30:55", tz_offset=9) # The reason that I add tz_offset=9 is to make local time samw with `Asia/Seoul`
    def test_freeze_time1(self):
        print("TIME_ZONE='UTC', USE_TZ=True")
        print(datetime.now())
        print(timezone.now())


    @override_settings(TIME_ZONE='UTC', USE_TZ=False)
    @freeze_time("2018-01-04 13:30:55", tz_offset=9)
    def test_freeze_time2(self):
        print("TIME_ZONE='UTC', USE_TZ=False")
        print(datetime.now())
        print(timezone.now())


    @override_settings(TIME_ZONE='Asia/Seoul', USE_TZ=True)
    @freeze_time("2018-01-04 13:30:55", tz_offset=9)
    def test_freeze_time3(self):
        print("TIME_ZONE='Asia/Seoul', USE_TZ=True")
        print(datetime.now())
        print(timezone.now())


    @override_settings(TIME_ZONE='Asia/Seoul', USE_TZ=False)
    @freeze_time("2018-01-04 13:30:55", tz_offset=9)
    def test_freeze_time4(self):
        print("TIME_ZONE='Asia/Seoul', USE_TZ=False")
        print(datetime.now())
        print(timezone.now())

结果

TIME_ZONE='UTC', USE_TZ=True
2018-01-04 22:30:55
2018-01-04 13:30:55+00:00

.TIME_ZONE='UTC', USE_TZ=False
2018-01-04 22:30:55
2018-01-04 22:30:55

.TIME_ZONE='Asia/Seoul', USE_TZ=True
2018-01-04 22:30:55
2018-01-04 13:30:55+00:00

.TIME_ZONE='Asia/Seoul', USE_TZ=False
2018-01-04 22:30:55
2018-01-04 22:30:55

奇怪的部分是test_freeze_time1()，在 下进行测试TIME_ZONE='UTC', USE_TZ=True，我认为奇怪的原因是它datetime.now()没有打印出UTC时间，如果我删除了这不是真的@freeze_time("2018-01-04 13:30:55", tz_offset=9)：

from django.test.utils import override_settings

class TimeZoneTest(TestCase):

    @override_settings(TIME_ZONE='UTC', USE_TZ=True)
    def test_freeze_time1(self):
        print("TIME_ZONE='UTC', USE_TZ=True")
        print(datetime.now())
        print(timezone.now())


    @override_settings(TIME_ZONE='UTC', USE_TZ=False)
    def test_freeze_time2(self):
        print("TIME_ZONE='UTC', USE_TZ=False")
        print(datetime.now())
        print(timezone.now())


    @override_settings(TIME_ZONE='Asia/Seoul', USE_TZ=True)
    def test_freeze_time3(self):
        print("TIME_ZONE='Asia/Seoul', USE_TZ=True")
        print(datetime.now())
        print(timezone.now())


    @override_settings(TIME_ZONE='Asia/Seoul', USE_TZ=False)
    def test_freeze_time4(self):
        print("TIME_ZONE='Asia/Seoul', USE_TZ=False")
        print(datetime.now())
        print(timezone.now())

结果

TIME_ZONE='UTC', USE_TZ=True
2018-02-13 09:10:49.715005
2018-02-13 09:10:49.715018+00:00

.TIME_ZONE='UTC', USE_TZ=False
2018-02-13 09:10:49.715970
2018-02-13 09:10:49.715980

.TIME_ZONE='Asia/Seoul', USE_TZ=True
2018-02-13 18:10:49.716758
2018-02-13 09:10:49.716769+00:00

.TIME_ZONE='Asia/Seoul', USE_TZ=False
2018-02-13 18:10:49.717475
2018-02-13 18:10:49.717486

正如您在此处看到的，两者都UTC在条件下打印出时间TIME_ZONE='UTC', USE_TZ=True。

其他设置似乎运行良好。

或者，我错过了什么吗？
