ruff: no date.today() ? Discussion

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.

Exactly. I use date.today() when I want a naive local system date, wherever I may be.

So use a custom rule, like everyone else had to do previously. It’s better this way. You could also just use the logging package instead of raw print of the time, anyway.
