1173023272,I_kwDOCGYnMM5F6uoo,416,Options for how `r.parsedate()` should handle invalid dates,638427,mattkiefer,closed,0,,,,,11,2022-03-17T23:29:55Z,2022-05-03T21:36:49Z,2022-03-21T04:01:39Z,NONE,,"Exceptions are normal expected behavior when typecasting an invalid format. However, r.parsedate() is really just re-formatting strings and keeping the type as text. So it may be better to print-and-pass on exception so the user can see a complete list of invalid values -- while also allowing for the parser to reformat the remaining valid values.

In this case, I had just one variation of an invalid date: '  /  /  '. But theoretically there could be many values that would have to be fixed one at a time with the current exception handling.
