Falsehoods Programmers Believe In: Timezones, Names, Networks & Distributed Truths

Every engineer writes a bug rooted in an implicit real-world assumption. Inspired by Kevin Deldycke's iconic open-source repository, we deconstruct why UTC offsets shift, monotonic clocks prevent negative timestamps, and names cannot be split by space.

# Production Pattern: Monotonic Clock prevents NTP skew
import time
start_mono = time.monotonic()
execute_idempotent_operation()
elapsed = time.monotonic() - start_mono # Guaranteed >= 0.0
