Rasa ReminderScheduled makes the program crash, error with timezone - python-3.x

Question

I tried to use Rasa's ReminderScheduled as specified in the docs. I'm using Windows 10 with the Ubuntu subsystem to run the code. The code that calls the reminder is the following:
export_timeout = datetime.timedelta(seconds=30)
class ActionGiveListProducts(Action):
def name(self):
return 'action_give_list_products'
def run(self, dispatcher, tracker, domain):
s = getInfo("listeproduits")
dispatcher.utter_message(s)
return [ReminderScheduled("action_export_logs", datetime.datetime.now() + export_timeout)]
Executing this Action causes the following error:
Traceback (most recent call last):

'Unable to determine the name of the local timezone -- you must explicitly '
ValueError: Unable to determine the name of the local timezone -- you must explicitly
specify the name of the local timezone.
Please refrain from using timezones like EST to prevent problems with daylight saving time.
Instead, use a locale based timezone name (such as Europe/Helsinki).
I tried to set the timezone in the launch code as following:
os.environ['TZ'] = 'Europe/London'
time.tzset()
but this didn't change anything. I also searched for other solutions, but found nothing relevant.
Does someone know what causes this error exactly and if there is way to eliminate it?

Answer 1

I assume you run this in a Linux environment (as I had the same error), so try to set the following:
keep as you had it in the python code:
keepos.environ['TZ'] = 'Europe/London'
and also set the timezone in the os:
sudo cp /usr/share/zoneinfo/Europe/London /etc/localtime
It worked for me.

Answer 2

The following works on the Ubuntu subsystem for Windows:
sudo cp /usr/share/zoneinfo/America/New_York /etc/localtime
TZ=America/New_York rasa x
You can also make the TZ environment variable permanent by adding export TZ=America/New_York in your ~/.bashrc file.
