Issue with dependencies

Hello,

I add the UNIX timestamp to the item using an item pipeline. In essence, my code is:

import datetime

item['timestamp'] = datetime.datetime.now(datetime.timezone.utc())

Although datetime comes pre-installed with Python on my machine, it was not available on Scrapinghub, and, therefore, resulted in errors. I used the instructions ast https://support.scrapinghub.com/support/solutions/articles/22000200400-deploying-python-dependencies-for-your-projects-in-scrapy-cloud to include datetime as a dependency in the requirements.txt file. After deploying my project to Scrapinghub I got the error that now() does not exist in datetime.datetime.

What am I doing wrong here? Am I missing something?
