ZoneInfo('UTC') doesn't work

[stonebig]

ZoneInfo('UTC') doesn't function.

does this solution that is two weeks old may apply also for shiny-py ? https://github.com/jupyterlite/xeus-python-demo/issues/7#issuecomment-1375379923

>>> from zoneinfo import ZoneInfo
utc = ZoneInfo('UTC')
Traceback (most recent call last):
  File "<frozen importlib._bootstrap>", line 241, in _call_with_frames_removed
  File "<frozen importlib._bootstrap>", line 1050, in _gcd_import

  File "<frozen importlib._bootstrap>", line 1004, in _find_and_load_unlocked
ModuleNotFoundError: No module named 'tzdata'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<exec>", line 2, in <module>
  File "/lib/python3.10/zoneinfo/_zoneinfo.py", line 43, in __new__
    instance = cls._weak_cache.setdefault(key, cls._new_instance(key))

    raise ZoneInfoNotFoundError(f"No time zone found with key {key}")
zoneinfo._common.ZoneInfoNotFoundError: 'No time zone found with key UTC'

In order to make this work, you can run:

import micropip
await micropip.install("tzdata")
import tzdata
from zoneinfo import ZoneInfo
utc = ZoneInfo('UTC')
