# Log in into the box
vagrant ssh

# VirtualBox syncs host time with guest, so we need to shut off VBox Guest Additions first
sudo service vboxadd-service stop

# Now you can set any date and time
sudo date -s "2020-10-01 10:25:00"

  # Our architecture didn't allow us
  # to customize message body in a right way.
  # That is why we fuck it up right here.
  def fuck_short_url(text)
    return nil unless text
    # Offer short url in email should differ from generic one
    # Additional parameters should be included:
    # share_specific_short_url includes {source: 'email', email_shared_with: email}
    # Sometimes we can not avoid this hack because of the following usecase:
    # When user is sharing offer via email though talkable offer page
