BUG: warning shown when parsing delimited date string even if users can't do anything about it by MarcoGorelli · Pull Request #50232 · pandas-dev/pandas (original) (raw)

If anything, maybe Timestamp should become stricter and only accept iso8601 strings?

id be OK with more strict than the status quo (problems have been caused by the parsing code accepting "t2m", though Timestamp still rejects that as OOB for nanosecond reso). iso8601-only is probably too strict for my tastes

long long ago i wrote a dateutil-like parser that passed all/most of the dateutill tests and IIRC it was mostly just a handful of regexes (and appreciably more performant). ill see if i can dig that up.
