timezone issues with show name in past CRIDs

[hairmare]

Depending on CEST/CET, the show name doesn't match. There is a bunch of timezone related code involved, and due to several historic implementations there is a lot of converting going on that should be looked into.

this is the minimal reproducer for radiorabe/suisa_sendemeldung#528

import cridlib
from datetime import datetime
import pytz

timestamp_utc = pytz.utc.localize(
    datetime.strptime("2024-01-16 23:01:16", "%Y-%m-%d %H:%M:%S"),
)

crid = cridlib.get(timestamp=timestamp_utc)

print(crid)
assert "klangbecken" in str(crid)

The consumer needs to tell CRIDlib where we are:

import cridlib
from datetime import datetime
import pytz

timestamp_utc = pytz.utc.localize(
    datetime.strptime("2024-01-16 23:01:16", "%Y-%m-%d %H:%M:%S"),
)

crid = cridlib.get(timestamp=timestamp_utc.astimezone(pytz.timezone("Europe/Zurich")))

print(crid)
assert "klangbecken" in str(crid)

Maybe CRIDlib should astimezone on it's own in the get.past case? 🤔

DoD (both with and w/o TZ=UTC)

import cridlib
from datetime import datetime
import pytz

timestamp_utc = pytz.utc.localize(
    datetime.strptime("2024-01-16 23:01:16", "%Y-%m-%d %H:%M:%S"),
)
crid = cridlib.get(timestamp=timestamp_utc)
assert "crid://rabe.ch/v1/klangbecken#t=clock=20240116T230116.00Z" == str(crid)

timestamp = pytz.utc.localize(
    datetime.strptime("2024-01-16 23:01:16", "%Y-%m-%d %H:%M:%S"),
).astimezone(pytz.timezone("Europe/Zurich"))

crid2 = cridlib.get(timestamp=timestamp)
assert "crid://rabe.ch/v1/klangbecken#t=clock=20240116T230116.00Z" == str(crid2)
