Timezone America/Sao_Paulo triggers recursion errors in tests. #515

Open parona-source opened 1 year ago

parona-source commented 1 year ago

Whilst I was looking into https://bugs.gentoo.org/877603 (which ended up being the previously reported https://github.com/spulec/freezegun/issues/513) I tried to test TZ="America/Sao_Paulo" which failed quite horribly with recursion errors.

SarthakNikhal commented 1 year ago

Can I work on this issue?

parona-source commented 1 year ago

@SarthakNikhal You don't need permission to work on issues if you feel so inclined. Currently just don't think changes would be merged.

https://github.com/spulec/freezegun/pull/511#issuecomment-1748219731

So it may be wasted effort to fix this, unless you are doing it to learn of course.

bblommers commented 11 months ago

@SarthakNikhal @parona-source There are maintainers around now, so PR's are welcome.
