> 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.
> h3. Spec
> ||Pattern||Meaning||Additional details||
> |HH12|Hour of day (1-12)|Same as HH|
> |HH|Hour of day (1-12)|{panel:borderStyle=none}
> - One digit inputs are possible in a string to datetime conversion but needs
> to be surrounded by separators.
> - In a datetime to string conversion one digit hours are prefixed with a zero.
> - Error if provided hour is not between 1 and 12.
> - Displaying an unformatted timestamp in Impala uses the HH24 format
> regardless if it was created using HH12.
> - If no AM/PM provided then defaults to AM.
> - In string to datetime conversion, conflicts with SSSSS and
> HH24.{panel:borderStyle=none}|
