> Having a timestamp string in 12-hour format can be parsed if the hour is 0,
> however, based on the [design
> document|https://docs.google.com/document/d/1V7k6-lrPGW7_uhqM-FhKl3QsxwCRy69v2KIxPsGjc1k/edit],
> it should be rejected.
> h3. How to reproduce
> Run {code}select cast("2020-01-01 0 am 00" as timestamp format "yyyy-mm-dd
> hh12 p.m. ss"){code}
> It shouldn' t be parsed, as the hour component is 0.
