Django logger is logging logs with two different time , sometime in GMT and sometime in IST

Question

Django logger is logging logs with two different time, sometime with GMT and sometime with IST. IST is the localtime. Setting has not been changed between these two logs.

django logger from settings is printing these two logs in file:

2021-04-19 06:30:00,061 DEBUG  XXXXXXXXXXXXXX
2021-04-19 12:00:20,061 DEBUG  XXXXXXXXXXXXXX

django settings files contains:

    LANGUAGE_CODE = 'en-us'

    TIME_ZONE = 'Asia/Kolkata'

    USE_I18N = True

    USE_L10N = True

    USE_TZ = False
