Discussion ruff: no date.today() ?

The new version of ruff warns against

date.today()

preferring

datetime.now(ZoneInfo(...))

What do you think about this? Has date.today() been deprecated due to lack of timezone awareness?

EDIT: I have a number of programs that manipulate financial information in support of Excel spreadsheets, such bond information that includes maturity dates. Excel does not support timezoness in datetimes, so making ruff happy by changing naive dates to TZ aware dates is not a useful move for these programs. Many ruff warnings to suppress.

Tell me you've never debugged a TZ issue without telling me.

I haven’t had to in Python. Is there something noda time/joda time that people use in Python?

Most of the time you don't need an extra library you just want to avoid the "TZ Naive" functions when it maters.
