Hey @Jay2109 I think kraiiz abandoned the project, but I was having this same issue just now, and after quite a log of debugging I figured that it works, but the cron service is running in UTC time only which is a bit messy considering DST in some countries, so I still need to figure out how to change that to different timezones

ok so, if you are using docker like me, you can do this on your Dockerfile

RUN rm /etc/localtime
RUN ln -s /usr/share/zoneinfo/America/Lima /etc/localtime

In my case I set the timezone to America/Liima you can change that for whatever timezone you want
The path for the timezones might differ depending on the distribution you use. and for that Google is your friend

I solve my timezone used RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime in my dockerfile. it's work.

I am so surprised that this is still not working for me. Can you please take a look at below?

"crontab -l" shows my cron job correctly
I have also created a symbolic link by using "RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime"

and this is my dockerfile:

`FROM python:3.9.2-alpine

set work directory

WORKDIR /usr/src/app

set environment variables

ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1

install dependencies

RUN pip install --upgrade pip
COPY ./requirements.txt .
RUN pip install -r requirements.txt

copy project

COPY . .

#Creating a soft symbolic link with force option (-sf)
RUN ln -sf /usr/share/zoneinfo/Asia/Kolkata /etc/localtime

EXPOSE 8800
RUN python manage.py crontab add
CMD ["python", "manage.py", "runserver", "0.0.0.0:8800"]`

It's a pity, but the project is dead. Can anyone recommend a cron for django?
