With Miroslav, we dissected the pytz library, as he explained why it contains over 400 individual time zones while focusing on the Europe/Tallinn entry. He also discussed the reason why pytz is not part of the standard Python, why it gets updated so often and why even that won't solve all your problems. He covered two centuries of short-sighted propaganda and long-term chaos in less than thirty minutes.
