Working with Time Zones - Everything You Wish You Didn't Need to Know

Explore the complexities of working with time zones in Python through this informative PyCon US talk. Delve into Python's time zone model and learn critical concepts to avoid datetime troubles. Discover how to handle ambiguous and imaginary times, perform datetime arithmetic around Daylight Savings Time transitions, and utilize datetime's fold attribute introduced in Python 3.6. Gain insights into the zoneinfo module from Python 3.9, understanding walltime and absolute time semantics. Cover various time zone abstractions, types, and the concept of local time. Learn about the deprecation of PyTZ and how to effectively bring your own data when working with time zones in Python.
