Usage:
16
16
# Always parse HTML top1000.html, then fallback for missing offsets
17
-
python generate_airport_tz_list.py --html top1000.html --out src/c/airport_tz_list.c --top 10 --max-bucket 3

-
Dependencies:
20
-
pip install airportsdata beautifulsoup4 pandas requests
21
-
22
-
This script intentionally re-implements the DST-transition detection logic from
23
-
`generate_tz_list.py` so it can remain self-contained.
